I have found clinics vary greatly from one to the next. One clinic wanted me to use biofeedback and meditation and the next would want me on morphine. If you are having trouble with them, first try to talk to them. if you get no where, ask your MD to refer you to another if any are in your area. I had to travel 45 mins in one direction for the last clinic I went to, but it was well worth it to be treated with respect and kindness, instead of like a drug seeking maniac.
I hope you feel better.
