I understand why the doctors can't spend that much time with you but it drives me crazy is that this kind of medical practicing is causing a huge problem so RUN from this practice because there are doctors that will take the time. This is so important for you at this time. You don't say where you are located as it would be nice to have someone close.
Have you tried acupunture? This has been my saving grace. Also, have you worked with a DO (Doctor of Osteopathy) who wants to make sure that everything is in working order and not just to treat the symptoms. Sometimes with pain you can manage some of it by managing other areas of the body. Acupunture is the way to go as that is what they do, treat the meridians that run through body and clear them so that the body can help to heal itself.
If you are in the OC area, Dr. Moon is over under the John Wayne Airport fly zone, off of the 73 fwy at Campus. ###-###-####
My DO is Dr. Mary Berry in Anaheim Hills ###-###-####
