Question:
I fell off my bike and landed on the inside of my right knee. Never any real pain, no loss of function or dexterity, But I seem to have a "blister" under my skin. It is fluid of some kind. It's nothing more than a little annoying but I am starting to worry as it has been 2 months and it wont go away. Anyone ever heard of this kind of thing?
Answers:
its probably nothing more than a deep contusion, or bruise. The knee, like many other joints work through diffusion to get its blood supply, not direct supply via veins and the like. because of this, less oxygen gets through at a time and injuries take longer to heal. Also, bruises themselves heal by the dead blood cells that make up the bruise slowly being carried away back into the blood stream. Again, Since joints get blood differently, to completely heal could take a very long time. If you bruised you knee internally, or ruptured a minor blood vessel then the time it take s to heal will really depend. I dont believe though that its anything to be concerned about. Should you however, feel any numbness or tingling or develop pain you should of course seek medical attention
