For the last week to 2 weeks I've had a pins and needles and numbness on and off over a large patch of my thigh. It is getting worse and today is very numb and feels heavy. It doesn't look any different, not hot to touch etc... but is very uncomfortable now. I have been in and out of hospital the last few weeks with weight loss so not sure if this has anything to do with it, and am of course hardly active at all as I have been so ill. Does anyone have any ideas? There's not any g.p. appts for a few weeks.
