I’m sorry but I don’t have experience or knowledge of any of the particular complaints you have been diagnosed with, not even the sinus problems but I know many on here have. Your thin blood vessel walls I have come across in passing, is your skin translucent ? Have you been checked for EDS ?
You certainly have hypermobility from the sound of it and that, plus the blood vessel thing is a collagen issue. Do you get much meat, fish, poultry, eggs, nuts in your diet, essentially every day and what’s your intake of fresh fruit and veg like ? Both of these are very important to help make good collagen.
Also try to get 2-3grams of iodised salt every day, otherwise it may be irrelevant what you eat, as it won’t be being digested and absorbed properly.
