<s>[INST] 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. [/INST] 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. </s>
