Most knee pain improves with a combination of rest, targeted exercises, and simple lifestyle changes you can start today. The right approach depends on what’s causing your pain and where exactly you feel it, but the basics work for nearly every type of knee problem: reduce inflammation, strengthen the muscles that support the joint, and avoid activities that make things worse while you heal.
Start With Rest, Ice, and Elevation
For knee pain that’s recent or flaring up, the classic RICE approach (rest, ice, compression, elevation) is your first move. Apply ice or a cold pack for 10 to 20 minutes, three or more times a day. When you’re sitting or lying down, prop your leg on pillows so your knee stays at or above heart level to help drain swelling. A compression bandage or sleeve can also keep fluid from pooling around the joint.
This isn’t a long-term fix, but it calms acute inflammation and buys you time to figure out your next steps. Most minor knee injuries and flare-ups improve noticeably within a few days of consistent icing and rest.
What the Location of Your Pain Tells You
Where your knee hurts is a useful clue about what’s going on. Pain at the front of the knee, around or behind the kneecap, often points to overuse problems like runner’s knee, cartilage softening under the kneecap, or a tracking issue where the kneecap doesn’t glide properly. This type of pain is common after starting a new exercise routine or ramping up activity too quickly.
Pain on the inner side of the knee usually involves cartilage or ligament damage, particularly the medial collateral ligament or the meniscus, the rubbery cushion between your bones. Pain behind the knee can signal a fluid-filled cyst (called a Baker’s cyst), hamstring tendon inflammation, or a cruciate ligament injury. Lateral (outer) knee pain often relates to the IT band or the lateral meniscus.
Knowing the location helps you and your doctor narrow down the cause, which shapes everything from which exercises will help to whether you need imaging.
Over-the-Counter Pain Relief
For day-to-day pain management, acetaminophen (Tylenol) is a reasonable starting point. It handles pain without the stomach and kidney risks that come with anti-inflammatory drugs. Anti-inflammatory options like ibuprofen and naproxen are more effective when swelling is part of the picture, since they reduce inflammation directly, but they carry real downsides with regular use: stomach ulcers, kidney strain, and increased bleeding risk. These risks climb significantly for people over 60 or anyone with a history of stomach problems.
If you find yourself reaching for pain relievers daily for more than a couple of weeks, that’s a signal to look beyond medication at the structural and lifestyle factors driving your pain.
Strengthen the Muscles Around Your Knee
This is the single most effective long-term strategy for most knee pain. Strong muscles absorb shock so your joint doesn’t have to. A basic knee conditioning program takes four to six weeks and should be done two to three days a week at minimum to maintain strength and range of motion. Always warm up with 5 to 10 minutes of walking or stationary cycling before you start.
Here are exercises recommended by the American Academy of Orthopaedic Surgeons:
- Shallow squats: Stand with feet shoulder-width apart, slowly lower your hips about 10 inches as if sitting into a chair, hold for 5 seconds, then push back up through your heels. Three sets of 10, four to five days a week.
- Calf raises: Stand on your affected leg, holding a chair for balance. Raise your heel as high as you can, then lower. Two sets of 10, six to seven days a week.
- Standing quad stretch: Hold a chair for balance, bend your knee and pull your heel toward your buttock. Hold 30 seconds. Two to three reps, four to five days a week.
- Heel cord stretch: Face a wall with one foot forward (knee slightly bent) and the affected leg straight behind you, heel flat. Press your hips toward the wall and hold for 30 seconds. Two sets of four, six to seven days a week.
- Hamstring stretch: Lie on your back with both knees bent, then gently straighten the affected leg upward. Two to three reps, four to five days a week.
Stretching matters as much as strengthening. Tight muscles around the knee pull on the joint unevenly, which accelerates wear and creates pain even when there’s no acute injury.
Switch to Low-Impact Cardio
If running or high-impact sports triggered your knee pain, you don’t have to stop moving. You just need to choose activities that keep your heart rate up without hammering the joint. The best options:
- Cycling builds leg strength and keeps the heart healthy with minimal knee stress.
- Elliptical machines provide a smooth gliding motion that avoids the jarring impact of running.
- Rowing machines combine cardio and strength training while letting your knees move through their full range of motion.
- Swimming and water aerobics reduce weight-bearing almost entirely while still providing a solid workout.
- Pilates strengthens the core and improves balance through controlled movements that are easy on the knees.
Staying active is critical. Resting too much actually weakens the muscles that protect your knee, setting you up for more pain down the road.
Lose Weight If You’re Carrying Extra
This one is straightforward but powerful. Being just 10 pounds overweight increases the force on your knee by 30 to 60 pounds with every step. That math works in reverse too: losing 10 pounds takes 30 to 60 pounds of pressure off your knees during walking, stair climbing, and everything else you do on your feet. For people with osteoarthritis, weight loss alone can make the difference between constant pain and manageable discomfort.
Do Supplements Help?
Glucosamine and chondroitin are the most popular joint supplements, and the evidence is genuinely mixed. A combined analysis of 29 studies involving over 6,000 people with knee osteoarthritis found that glucosamine and chondroitin each reduced pain when taken separately, but not when combined. The catch: results varied wildly between individual studies, and the type of supplement mattered. Prescription-grade or pharmaceutical-grade formulations consistently outperformed the store-bought versions.
Major medical organizations disagree on whether to recommend them. The American College of Rheumatology recommends against glucosamine for knee osteoarthritis, citing weak evidence. The American Academy of Orthopaedic Surgeons says supplements including glucosamine may help mild-to-moderate cases but cautions that evidence is inconsistent. If you try them, give it at least two to three months, and know that the pharmacy-brand version in the supplement aisle is not the same formulation that showed the best results in studies.
Injections and Medical Options
When home care and exercise aren’t enough, injections are a common next step. Cortisone injections control inflammation and pain for several weeks to months. It can take up to a week after the shot to feel improvement. If one or two cortisone injections don’t help, additional shots are unlikely to work either.
Hyaluronic acid injections (sometimes called gel shots) act as a lubricant and shock absorber inside the joint. Some people get months of relief, but not everyone responds. Neither type of injection fixes the underlying problem; they buy time for rehabilitation or provide relief while you explore other options.
Signs You Need Urgent Care
Most knee pain is safe to manage at home initially, but certain symptoms need immediate attention. Get to urgent care or an emergency room if your knee joint looks visibly bent or deformed, you heard a popping sound at the time of injury, your knee can’t bear weight at all, the pain is intense, or the knee swelled up suddenly. A fever alongside knee pain could indicate an infection in the joint, which is a medical emergency.
