You stand up after sitting a while… and there it is, that sharp twinge in your knee. Maybe it shows up when walking uphill, getting out of bed, or going down the stairs. It doesn’t seem serious at first, but it keeps showing up, tighter, stiffer, and more frustrating each day.
Knee pain is one of the most common joint issues people face, and it doesn’t always come from a big injury. Sometimes it builds up from small, everyday habits or wears over time.
In this article, we’ll look at what actually causes knee pain, what daily mistakes quietly make it worse, how to find quick relief, when it’s time to see a specialist, and how small changes like using the right compression support can help you move more easily again.
Why Does My Knee Hurt All the Time?
It’s not always a big injury that causes knee pain, sometimes, it builds up quietly over time. Let’s walk through the real reasons behind it and what your knee might be trying to tell you.
I didn’t even fall, so why is my knee hurting so much?
That’s a common question. Many people are surprised to feel pain even when they haven’t twisted, fallen, or pushed too hard. But knee pain isn’t always about one big event, it can be a slow build-up of strain, wear, and small missteps that add up.
Here’s a clear breakdown of why your knee might hurt, even if your life seems normal on the surface:
Osteoarthritis
A slow breakdown of joint cartilage, mostly in people over 45. Osteoarthritis causes stiffness, swelling, and that deep ache after walking or standing.
Around 2.1 million Australians (8.3%) reported living with arthritis, according to the 2022 National Health Survey by the Australian Bureau of Statistics (ABS, 2023).
Ligament issues
Injuries to the ACL or MCL, even minor ones, can lead to pain and a feeling of instability, especially on stairs or uneven ground.
Meniscus tears
Meniscus tears happen when the soft cushion in your knee, the meniscus, gets damaged from twisting, squatting, or sudden movement. You might hear a clicking sound or feel pain behind the knee when walking.
Chondromalacia patella
Chondromalacia patella is the fancy term for when the cartilage under your kneecap starts to wear down. It usually shows up when your knee hurts when bent, like going downstairs or sitting for long periods.
Tendon problems
Tendons can get overused and irritated (especially the patellar tendon), causing pain just below the kneecap that flares up during activity.
Old injuries
A past twist or strain you thought was “nothing” might still be messing with your joint years later.
Rare causes
Cysts, nerve issues, or even bone diseases are rare, but if your knee is swollen, red, or painful without reason, talk to your GP.
Extra body weight
Every 1kg gained = up to 4kg of extra load on the knees per step. That adds up fast and wears the joint out quicker.
Inflammatory conditions
Rheumatoid arthritis and gout can cause sudden swelling, sharp pain, and hot joints, often in flares, not just daily wear.
You might notice it when you bend your knee, go downstairs, or even just stand after sitting for a while. If your knee hurts when bent or you feel pain behind the knee when walking, these patterns often point to one of the issues above.
Things We Do Every Day That Quietly Make Knee Pain Worse
Sometimes it's not a major injury, but the small, daily habits that quietly pile up pressure on our knees. Let’s break down a few of these common mistakes and what they really do to our joints.
My knee pain got worse after switching to a standing desk. What gives?
You’re not alone. Many people notice knee discomfort showing up during simple lifestyle changes, like walking more, standing longer, or even changing footwear, and often don’t connect it to their everyday choices. Here’s what might be happening behind the scenes:
Prolonged Sitting: Too Much Stillness Stiffens the Joint
Sitting for long hours at a desk, in the car, or watching TV can reduce blood flow, weaken the muscles around the knee, and cause the joint to stiffen.
- According to studies, prolonged inactivity can reduce joint lubrication, making the knee feel achy or tight.
- This kind of stiffness is often mistaken for aging, when in reality, it’s a movement issue.
Small change: Set a timer every 30–60 minutes to stand, stretch, or walk for just a minute or two.
Climbing or Descending Stairs Frequently: High Impact, Hidden Strain
Using stairs all day might feel like great exercise, but it places about 3-4 times your body weight across the knee joint with each step, especially when descending. This can worsen pain in people with patellofemoral pain syndrome or cartilage thinning.
- A study published in Proceedings of the Institution of Mechanical Engineers shows that stair descent generates 3.1 × body weight compressive forces on the knee than flat walking.
If your knee hurts when bent or during stairs, take breaks or use a handrail for support.
Skipping Stretching or Strength Training: Weak Muscles = Overloaded Knees
When your hips, quads, and hamstrings are weak or tight, your knees take on the load. Without regular movement or muscle balance, the knee joint becomes less stable, which leads to more pain and faster wear.
- The American Academy of Orthopaedic Surgeons recommends simple strengthening and mobility exercises to reduce pressure on the knees by supporting them better.
Even short daily movements, like leg raises or seated hamstring stretches, can help ease joint strain and improve knee pain relief.
Improper Lifting: Strain Without Realising It
Bending from your waist instead of your knees to lift heavy objects can push your body weight straight into the joints.
- Over time, this can aggravate tendons or stress the joint surfaces, especially in people who already feel pain behind the knee when walking or bending.
Tip: Always bend your knees and keep the load close to your body.
Wearing Unsupportive Footwear: It Starts from the Ground Up
Flat, hard shoes or worn-out soles can change your natural walking pattern (gait), causing misalignment and joint pressure that travels upward into your knees.
- Podiatrists often highlight that footwear without arch support or shock absorption increases joint fatigue, especially for those walking or standing on hard floors.
Swap them out for cushioned, supportive footwear if you're on your feet often, especially on concrete or tile.
Standing or Walking on Hard Surfaces for Long Periods
Whether you're at work, in a store, or using a standing desk, hard surfaces amplify joint impact with every step or stance. Over time, this adds up.
Solution: Use a padded mat under your feet or supportive shoes with proper shock absorption.
Carrying Extra Weight: More Load, More Wear
Every step you take multiplies the pressure on your knees. Even just 5 extra kilograms can add over 20kg of force across each knee per step.
Maintaining a healthy weight helps reduce this load naturally and protects your joint structure over time.
Ignoring Early Discomfort: Waiting Makes It Worse
Mild knee soreness is often dismissed until it turns into a persistent issue. But early care, like rest, stretching, or wearing knee compression wraps, can often prevent more serious damage.
If you feel discomfort regularly while walking, lifting, or standing, don’t push through it; adjust your habits before it builds up.
What Is the Fastest Way to Relieve Knee Pain?
Not everything works overnight, but when your knees are flaring up, a few simple steps can calm things down fast. Here's what actually works and why.
Rest (But Not Total Rest)
If your knee starts hurting, the first instinct might be to stop moving entirely. But full immobility can make stiffness worse. Instead, rest in short intervals and avoid actions that increase pain, like squatting, running, or kneeling, especially in the first 48 hours after a flare-up or minor injury.
- Relative rest (reducing movement but staying mobile) helps the joint recover without losing flexibility or strength.
- Listen to your knee: short breaks help more than lying down all day.
Apply a Cold Compress
Cold helps slow down inflammation and dull sharp pain by temporarily reducing blood flow.
- Wrap an ice pack or a bag of frozen peas in a towel and place it on your knee for 15–20 minutes, several times a day.
- Never apply ice directly to the skin.
This is especially helpful after an activity, injury, or swelling that feels warm to the touch.
Compression for Stability and Swelling
Using a knee sleeve, knee-high compression stockings, or an elastic bandage helps reduce swelling and keeps the knee joint supported throughout the day.
- Compression promotes better circulation and reduces fluid buildup.
- It’s a go-to recommendation in the RICE method (Rest, Ice, Compression, Elevation) used widely by physios and sports trainers.
If you're walking a lot or working long hours on your feet, compression wraps can be a big help.
Elevate Your Leg
Lifting your knee above the level of your heart can help drain excess fluid and reduce swelling.
- Use pillows to support your legs while lying down, especially in the evening.
- Elevation works best when paired with ice or compression.
This combo can bring quick relief for joint pain, especially after standing for hours or walking long distances.
Gentle Stretching and Muscle Activation
Once the swelling eases, a little movement helps keep the knee from stiffening. Gentle movements also wake up the muscles around the knee and help maintain strength.
Try:
- Straight leg raises
- Seated knee extensions
- Calf stretches against a wall
These exercises reduce load on the joint by activating supportive muscles. Always avoid any movement that triggers sharp pain.
Over-the-Counter Pain Relief (Short Term Use)
NSAIDs like ibuprofen or naproxen help reduce both pain and inflammation. Use them with care and only for short-term relief, as overuse may affect kidney or stomach health.
- The Institute for Quality and Efficiency in Health Care notes that NSAIDs are effective in reducing knee pain when used correctly and combined with physical strategies.
Always follow label directions or check with your doctor if you have other health conditions.
Self-Massage
Massaging the thigh, calf, or the area around the knee can ease muscle tightness and promote blood flow.
- Foam rollers or gentle hand massage can help you feel looser and reduce pressure across the joint.
This can be especially useful after sitting for long hours or standing on hard floors.
Supportive Footwear Makes a Big Difference
Shoes with proper arch support and cushioning absorb shock and keep your gait balanced. If your shoes are flat, thin-soled, or worn out, they could be increasing pressure on your knees with every step.
What If It Doesn’t Go Away? When You Should See a Specialist
Most knee pain gets better with rest, light movement, and simple care, but not always. If it lingers or keeps coming back, that’s your sign to check in with someone who deals with this every day.
Pain that sticks around isn’t something to ignore. It doesn’t always mean surgery; sometimes all you need is the right diagnosis and a proper plan. Here are the key signs it's time to speak to a professional:
1. Pain Lasting More Than a Few Weeks
If your knee’s been hurting for over 2–3 weeks despite rest, icing, and movement adjustments, it’s time to get it looked at. Persistent discomfort often points to an underlying issue that won’t clear up on its own.
2. Pain Disrupts Your Daily Routine
If walking, climbing stairs, or even standing for too long has become a challenge, don’t push through it. These are strong signs that your joint needs targeted support or treatment.
3. Swelling, Warmth, or Redness That Doesn’t Settle
These symptoms could mean inflammation, fluid buildup, or infection. Persistent knee swelling, especially if it feels hot or looks red, should be checked by a healthcare provider quickly.
4. Sudden, Severe Pain After an Injury
A fall, twist, or impact that causes sharp pain or popping sounds could involve ligament tears or meniscus damage. Don’t wait, seek help immediately if the pain is intense or movement feels restricted.
5. Feeling Like the Knee “Gives Out” or Locks
If your knee feels unstable, won’t straighten, or “catches” while moving, a specialist such as an orthopaedic doctor can help diagnose issues like ligament injury or cartilage problems.
6. No Relief from Self-Care
Tried ice, compression, rest, and OTC medication, and still not feeling better? That’s when it’s worth finding a knee injury doctor near you to guide the next steps.
A specialist might suggest imaging (like an MRI), physiotherapy, or joint-specific exercises. The earlier you get a clear diagnosis, the quicker you can start healing properly.
While waiting for a proper diagnosis, many people use compression stockings to manage swelling, improve circulation, and reduce discomfort. Not sure if they’re right for you? See our quick guide on what compression stockings do.

Frequently Asked Questions
What not to do during knee pain?
Avoid overloading the joint, like running, deep squatting, or lifting heavy objects without support. Skipping warm-ups, wearing unsupportive footwear, or sitting for hours without movement can quietly increase strain on the joint.
Should I keep my knee straight or bent?
If your knee is swollen or painful, it’s best to rest it slightly bent, not locked straight. This reduces tension while keeping some mobility in the joint. Avoid keeping it in one position for too long.
How to massage knee pain?
Use gentle circular motions around the thigh and calf muscles, not directly on the joint if it’s inflamed. You can also use a warm towel to relax the area first and improve blood flow during massage.
What is the best position to sleep in with knee pain?
Sleep on your back with a pillow under your knees or on your side with a cushion between your legs. Both positions reduce pressure and keep the joint in a neutral, supported position.
Is walking good for knee pain?
Yes, light walking helps improve circulation and keep joints moving. Just make sure you’re wearing supportive shoes and avoiding hard surfaces to minimise joint pressure.
