welcome to TiMS, pip. you'll find lots of information and support here. if you have any reason to suspect nutrition may play a part in your case, feel free to ask me questions. other than that i'd recommend lots of reading - it takes a while to make sense of everything out there and how it might or might not apply to your situation.
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
