So a little background- a month ago I blew out my back and went into er. Doctor ruled a back spasm and it would get better. I am overweight and work in a job where I stand/walk all day. Ten days ago my right thigh went numb- feeling like its asleep constantly. Tonight my left arm and all my fingertips (right and left) now feel the same... (Leg is still numb too)

What does it sound like? What should I do? Any home tests?

It sounds like pinched nerves. Have you ever considered going to a good chiropractor?
