I've been getting a pain in my left leg for a couple of days. It's sharp and is focused along the back of my calf and extends up to my pelvis into my back. I haven't been doing major sports and I don't think it's an injured muscle or anything. It doesn't change when i'm walking, standing or sitting down and sometimes extends right down my lower leg. It might even be linked to a lump in my lower pelvis which isn't apprant on look - but can be felt. There also seems to be an identical pain in my left arm, though this is not as common.

About two weeks ago though, I fell off the bottom step of out stairs and ended up in the lviing room (funny for all invovled except me.) my ankle buckled under me and hurt badly. The pain went away, mostly, after a couple of days though. Is it possible that something happened in my ankle which is linked to the new pain in my upper leg?

I also spend a lot of time sitting at the computer and, as I type with only my two index fingers, the fingers of my left hand are curled in with my idex finger pointing as I type.

Help would be greatly appreciated. I'm getting very worried.
