HELP! I just got a herniated disk – about a month ago which resulted in very painful sciatica. I got a cortisone injection – hurt like hell – and it relieved some of the pain – but it still has not gone completely, and I am still in some pain. Now the doctor wants to give me another injection. Oh my word. He said that I would still need about 2 more injections. If it then does not improve – I will need surgery. I am scared to death.
