1, rest-stop all sports that cause pain, especially running, long jumping and going up and down stairs.

2, ice-two or three times a day, put the plastic bag with crushed ice on your knees 15 minutes.

3. Take aspirin or ibuprofen-take 650mg aspirin or 400mg ibuprofen three times a day for 1-2 weeks to relieve inflammation. If you have stomachache or bloody stool during taking the medicine, please stop taking the medicine immediately.

4. Strength training-insufficient strength of thighs or buttocks is the main cause of anterior knee pain and iliotibial tract syndrome.
