About 12 days ago I banged the corner of my knee cap on a sharp edge of my desk very hard. That night when I removed my pants I noticed knee was swollen and very tender to the touch. I decided to let it heal naturally but in the following days the swelling spread until my lower leg from my knees to my toes became noticeably puffy, especially the top of my foot and inside of my ankle. At this point, 7 days from the time I banged my knee, I saw a GP. He had me get x-rays and I asked him to check for lime disease. The x-rays showed no fractures and the lime test was negative. He said my white blood cell count was slightly elevated, so in addition to an anti-inflammatory he prescribed an antibiotic.
In short neither seem to be doing any good. My knee is barely swollen and painless, but my foot and ankle are still inflated. I don't know whether I should see an orthopedist or give it more time. It really doesn't seem like anything is broken. Any advise or diagnosis would be greatly appreciated.
