I Have L4 L5 Herniated Disc And Spinal Stenoisis .

I have l4 l5 herniated disc and spinal stenoisis . I do get injections a few times a year but I was wondering why my doctor prescribes gabapentin for pain the stuff does nothing to relieve my pain nor do I read anything like it does. everything says good for pain after shingles bad rashes sometimes I miss work cause my back hurts so bad its a terrible life but all doctors are so afraid to give ya a pain reliever that really works like it was made for
