I have diabetes 2 and it has been fluctuating up and down mostly down after I take my meds . My 4th toe feels like it has a rubberband around it with slight tingling in my other toes I am on 300 mgs of gabipentin for fibemyalga. I also have back problems with nerve pain and tingling down into my toes I have had a cotizone injection in my rear on both sides which has taken away some of the nerve tingling. What may be the problem still?
