Knee Pain While Running

My knee has been hurt­ing when I run. When should I see a doctor?

Most ath­letes will expe­ri­ence some knee pain from time to time. Overuse, long train­ing days or bumps and bruis­es from con­tact sports often result in minor knee pain that heals with­in a day or two with some rest and ice. But there are some clues that indi­cate more seri­ous knee pain and injuries that may need to be seen by a doc­tor for a com­plete eval­u­a­tion and treat­ment plan. You should see a doc­tor for your knee pain if you have any of the fol­low­ing warn­ing signs: Pain that lasts more than 48 hours, swelling that lasts more than 48 hours, loss of range-of-motion in the joint, insta­bil­i­ty: feel­ing that the knee will give out, inabil­i­ty to put your full weight on the leg, or defor­mi­ty of the knee joint.
