Hi, I have posted on here several times in search of a diagnosis for my boyfriend. Doctors don't seem to be doing any good, as we have been going to them for years and done so many tests and I feel like they have given up on him. He has had a migraine from the morning til he gets to sleep for 4 days now. He isn't throwing up or anything, but he does have a lot of other symptoms and I'm wondering if it is all caused by something in his endocrine system. If you do know if there is a disease in the endocrine system that causes migraines as well as many other symptoms like digestive issues, fast heart rate and fatigue please let me know the name of the disease and I will look into it. Thank you
