I have seen amazing things done with hypnosis with regards to pain management. I have seen people incapacitated with pain able to regain real quality of life back with only 1 sesssion.
It seems to me that your problem is one of pain, in which case it can be entirely controlled by hypnosis.
My advice would be to find a qualified hypnotherapist near you who specialises in pain-management.
Once you have the pain under control, perhaps you can think about going about a "cure".
