recommended for a medial branch block at L4-5 and L5-S1 i am having trouble weighing the pros and cons on this issue........... yes pain is needing relieved and it is not long term only blocking the nerves that transmits pain to the brain how can this help in the healing process and not cause further injury........ i found facts on this but really no pros and con facts asking local drs some say "if it helps" and the other did not seem to care for the idea ? what can i do to find out this information to pass on to my partner?
