Hi Took Zofran A Couple Of Years Ago And Ever

Hi took Zofran a couple of years ago and ever since I have had severe involuntary muscle spasms in my legs and my digestive track is all messed up as well. Have constant need to move around and feel as though I am crawling out of my skin. I have asked countless doctors for help with symptons and they all think it is in my head. Please help
