<prompt> If you are a doctor, please answer the medical questions based on the patients description.My dog ran into the inner part of my left knee. Has been very sore since, especially when going down the stairs. I made the mistake of trying to run a few days after the injury and now, even several days later I am in excruciating pain. I have mild swelling, which ice is not alleviating.  <response>: Well, obviously, an anti-inflammatory. Aspire or naproxen are anti-inflammatories, Tylenol or ibuprofen at over the counter doses are not. BUT warm compresses may help. Certainly trying to elevate the leg and staying off it will help. BUT, it seems a lot of swelling and injury and duration of problem. There might be more occurring like damage to cartilage or tendons. IF persisting a week, an orthopedist is generally needed for evaluation.
