I'm sorry to hear that you are still suffering multiple issues, I assume the docs not sure how they all tie together, or what the catalyst was that started it all, since it has been so long for you.
When I had continued problems after my metal hips were replaced, it was a persistent primary care provider that helped me put the pieces together.
Who have you been seeing? Do you have an option to see a group, where the primary and specialists work together?
