Hi Martin is in constant pain on the side of the neck along the scar and in his shoulder. He has accepted this might the case forever now, but is trying all of the suggestions from the pain management team. So he tried botox. It had the reverse effect to start with and now it's the same as ever. The botox made his muscle cramp up and twitch and ache more. Has anyone else tried and seen a positive result? Pain team reckon it might work second time round.
