Tendinitis -- a pain in the front of your knee that gets worse when going up and down stairs or inclines
Torn cartilage (a meniscus tear) -- pain felt on the inside or outside of the knee joint
Torn ligament (ACL tear) -- leads to pain and instability of the knee
Strain or sprain -- minor injuries to the ligaments caused by sudden or unnatural twisting
Less common conditions that can lead to knee pain include bone tumors.
For knee pain that has just started:
Rest and avoid activities that aggravate your pain, especially weight bearing activities.
Apply ice. First, apply it every hour for up to 15 minutes. After the first day, apply it at least four times per day.
Keep your knee raised as much as possible to bring any swelling down.
Wear an ace bandage or elastic sleeve, which you can buy at most pharmacies. This may reduce swelling and provide support.
Take acetaminophen for pain or ibuprofen for pain and swelling.
Sleep with a pillow underneath or between your knees.
For knee pain related to overuse or physical activity:
Always warm up before exercising and cool down afterward. Stretch your quadriceps and hamstrings.
Avoid running straight down hills -- walk down instead.
Bicycle or swim instead of run.
Reduce the amount of exercise you do.
Run on a smooth, soft surface, such as a track, instead of on cement.
Lose weight if you are overweight. Every pound that you are overweight puts about 5 extra pounds of pressure on your knee cap when you go up and down stairs. Ask your health care provider for help losing weight.
If you have flat feet, try special shoe inserts and arch supports (orthotics).
Make sure your running shoes are made well, fit well, and have good cushioning.
Tips to relieve knee bursitis pain:
Use ice three to four times a day for the first 2 or 3 days. Cover your knee with a towel and place ice on it for 15 minutes. Do not fall asleep while using ice. You can leave it on too long and get frostbite.
Try not to stand for long periods of time. If you must stand, do so on a soft, cushioned surface. Stand with an equal amount of weight on each leg.
When you sleep, do not lie on the side that has bursitis. Place a pillow between your knees when you lie on your side to help decrease your pain.
Wear flat shoes that are cushioned and comfortable.
If you are overweight, losing weight may help.
When to Contact a Medical Professional
Call your doctor if:
You cannot bear weight on your knee
You have severe pain, even when not bearing weight
Your knee buckles, clicks, or locks
Your knee is deformed or misshapen
You have a fever, redness or warmth around the knee, or significant swelling
You have pain, swelling, numbness, tingling, or bluish discoloration in the calf below the sore knee

What to Expect at Your Office Visit
Your health care provider will perform a physical examination, with careful attention to your knees, hips, legs, and other joints.
To help diagnose the cause of the problem, your health care provider will ask medical history questions, such as:
When did your knee first begin to hurt?
Have you had knee pain before? What was the cause?
How long has this episode of knee pain lasted?
Do you feel the pain all the time, or off and on?
Are both knees affected?
Is the pain in your entire knee or one location, like the kneecap, outer or inner edge, or below the knee?
Is the pain severe?
Can you stand or walk?
Have you had an injury or accident involving the knee?
Have you overused the leg? Describe your usual activities and exercise routine.
What home treatments have you tried? Have they helped?
Do you have other symptoms, such as pain in your hip, pain down your leg or calf, knee swelling, swelling in your calf or leg, or fever?
The following tests may be done:
Joint fluid culture (fluid taken from the knee and examined under a microscope)
Your doctor may inject a steroid into the knee to reduce pain and inflammation.
You may need to learn stretching and strengthening exercises and podiatrist (to be fitted for orthotics).
In some cases, you may need surgery.
