I'm glad you have finally found a diagnosis I can relate to how frustrating it is not being heard for so long, something that helps me a little with the pain is keeping myself warm or at least trying to keep a steady temperature and light excersise, what I usually avoid is alcohol and heavy foods as I've found that makes the uneasiness and pain worse, also I've started using the progesterone only pill and it has really helped with the pain (I still feel the cramps and so on but with less intensity) if it is a option for you I'd advice to ask your doctor about the different types of the pill as they all have different side effects and might not be as effective as others.
