I had RLS for 1 year now but after taking iron and b12, I am quite fine with rls for the last 2 months. But have burning feet and sometime during in things and then it may come in legs. I am not diabetic and my all blood test were fantastic and even nerve conduction test are all fine. Just burning and sometime tingling in legs. If I go with pregabalin (I have not taken yet), is that habit forming or is this curable? I am worried sir. As I go out for workout, my feet start heating up.
