So today I tried an injection vaginally near my piriformis muscle, right side. Also external right lower abdomen. She said give it 48 hours to work. Its been burning a little now after a couple hours. Is it normal to have pain after this? I would think it would be instant relief. We are just grasping for straws at this point. My doc told me if this doesnt help we can retry in a month and then try gabapentin. I am about ready to give in to the pain and to start seeing a pain psychologist to learn how to deal with a lifetime of chronic pain.
