hiya EE03 you must have a pain management team very much unlike mine and you must be very lucky as, Mine told me i am now only allowed 2 per year as they are so expensive. over the last 3 sets of injections they have done a procedure, not sure what its called but they send pulses through the nerves as well and to be fair between the GON and the pulses they are lasting nearly 6 months now. have you spoken to your team about medication as well. my gp gives me diazapam if the pain get really bad where i cant cope, other medications i am on which do help are carbamazapine, co-codamol and omperazol, (the last one is just to help with stomache asid which is comon when on lots of medication) but try medication as well. hope this helps
