My pain management doctor tried both of those medications and neither of them worked for me either. Fortunately, my pain management doctor continuously provided me with pain pills so I could still reduce the pain. I found out that not all pain management doctors will prescribe pain pills. I recently had to change pain management doctors and the first 4 doctors I tried to see said they would not take me as a patient because I was prescribe pain pills and I have been pain pills for 4 years. I recommend calling the doctor and telling them the medication is not working, you are in a lot of pain and as them what you should do about it. They are supposed to relieve you of pain.
