I fell off a horse about a year ago and landed with all my weight (and some of the horses' weight) on my right knee. Though I was in pain, I could walk on it, so I rode out and continued the trail ride. About three weeks later, I was still experiencing pain and went to a doctor's office. After examining it and x-raying it he said I had a hematoma and told me to take ibruprofin and ice it daily. After a few weeks of treatment, it felt a lot better and the bruising went away. Since then, my knee has occasionally bothered me, especially when I'm very cold.
Two nights ago, I was at a haunted house where I had to crawl on my hands and knees through a tunnel. In progress of crawling, I had a sudden sharp pain in my knee and it is now hurting just like it did when I had the hematoma. A fairly large bruise has formed and it is painful to walk. I have knelt/crawled before with no pain. Has anyone heard of a returning hematoma? How should I treat this? Is it possible there was actually damage done that is now returning? Does having one hematoma make it more likely to get another?
