Am I losing my balance standing? (10 pts best answer)?

Hello, I'm 20 yrs old and I've recently had nerve pain I believe..random burning/stinging pain all over my body...it's been decreasing in the number of times it happens over the few weeks but I'm not sure if it is in my head or not but..when I stand still without moving my arms etc..my body sort of starts swaying towards the front or back...is this normal? this is a stupid question but I can't seem to get it off my mind.
