I have been to 2 pain clinics. The first one was a 2 week in hospital. That was years ago for Interstitial Cystitis. It was very complete. I had been suffering with extreme bladder pain, most by the damage they did to me as treatment. Using acid infusions to burn the lining out of my bladder and other tortures.
It was hard to let go of all the stress, but the volunteer mentor for each person was a pain clinic veteran. They started with guided imagery sessions that were very good. The tools used are learning how to do relaxation techniques, self hypnosis and meditation. Exercise and talk therapy included. Their were no drugs involved. Afterward I did 3, 1/2 hour meditations sessions everyday for 3 years. I am a controlling person, but did learn the techniques. There is no instant relief, but you can feel the results of the pain/brain connection being effected. Your unconscious brain can do amazing things. If you can make that connection and tell it what you want for your reality it can take you there.
I had had every possible treatment for my bladder, stretching, burning, DSMO instillation, tens machine and finally the doctor telling me I had to many ulcers to laser and I can do nothing for you. Every person has different outcomes. I could not take any pain meds.
11 years ago I had a new medical problem develop. I went to another pain clinic that was different, but based on the same principles. It was 1 week. It got me back into the mind/Body connection. But I needed medical help and 6 Gastroenterologists told me I had IBD and basically said goodbye. It was called pelvic floor dysfunction. Then 2 years of PT that was specifically for that. 1 Year of nerve blocks. Been to Davis, Stanford with no help. 2 years ago another doctor did a celiac test. Yes I have Celiac Disease. None of the Gastroenterologist knew about the Celiac autoimmune disease. I am now dealing with GF eating, but still have symptoms. Also a damaged body living in a state of malnutrition for 72 years.
The first clinic was the most complete and that is what I would look for. Most large Medical Hospitals have them. Also there are private ones. Go for those medical affiliated ones. The internet now is a great source. Most insurance will not pay, so it is very expensive.
If you believe you have everything in your body to make positive medical changes then go to a pain clinic.
