I'm fine with a neurologist referring me gastroenterologist for that area. I am NOT fine with doctors now using it as an excuse. They can't solve it, so they don't believe you. So they send you to someone else. If, as I have done, you have seen all these specialists, and you still get sent somewhere else. Or as the neurologist did, I didn't have Parkinson's Disease, which I am eternally grateful for, so they were done with me. It takes a patient's time and money to run around and see other doctors in specialties you have already seen. Or, back to one for something that was already diagnosed. If I lived close to Mayo Clinic, I would definitely go to their Fibromyalgia center. There is no cure, and some things just don't work. The battle against Fibromyalgia is on going and most of it is up to the patient. Find things that work.And do them.
