I had back surgery a year ago and I have been on Gabapentin ever since. I have nerve damage in both feet and right leg due to the disc that was removed. I havent been able to figure out why Ive had diarrhea thats progressively gotten worse and worse until a few days ago. Its the Gabapentin. The one thing I cant live without. Without it, my leg and feet burn and cramp and feel sporadic random stabbing tearing pains. But I have literally gotten to the point of not eating because every time I do, within minutes Im running to the bathroom. Literal minutes. Sometimes I cant get thru a whole meal and it does NOT matter what i eat. Fried chicken or lettuce. It doesnt discriminate. I dont understand this and Im gaining weight like crazy. How do you gain weight when everything you eat comes right back out momentarily? It makes no sense. Please Help!!
