About two years ago I started to notice a slight tingling/burning in my left outer thigh. It got a little bit worse when I had keys, cell phone, etc. in my left pocket. As of the past few months, I've noticed a numbness in my outer thigh. I feel pressure, and can feel touch when it's hard i.e. pinching. I think it's gotten worse because I have a job where I stand for 10-12 hours a shift.

I don't have any pain at all, just the numbness in the outer thigh. I'm curious what I should do?
