I have extreme amount of pain in my muscles right above my patella. This is happening on both legs. There is a noticeable amount swelling on both thighs, again right above my patella. My knees are fine, but my thighs hurt constantly. A few days ago, I was carrying laundry down a flight of stairs and miss the last step and fell, landing on my knees. The floor was concrete. I also use my laptop on my lap. Can this be a result from that or from the fall. It seems to be getting worse than better
