I recently had an epidural and since having it I've been having tremendous headaches that are severe enough to put br on the floor for 20 to 30 mins unable to move from the pain. I am on lorcet 10s for my back but they don't come close to helping the headache. I have been to the hospital 3 times this week with only a shot and prescription for something weaker than I already have. Can anyone tell me what could br causing this or what I can take or ask for to help please I can't handle this pain anymore
