Hi, Im a 36 year old healthy man. I have experienced chronic pain in my lower abdomin and lower back on the right side for approx 12 years. I was having intercostal blocks for years on and off however they would only help from time to time. The pain comes on like a contraction starting at zero and peaking at 10 then back down to zero all in about 10 sec. I can have this 3 times a min for an hour or two then it seems to settle down again. This can go on all day to weeks. The general thought was a torn muscle that had regrown with the nerve attached. The only specialist here that could administer intercostal blocks has been on extended stress leave for a few years and the pain seems to be not getting worse but the pain is constantly at the higher end now. Are there any alternatives?
