all i can suggest is nutrient testing.. my 'regimen' thread has a bloodwork section early on that might be useful, if you have a doctor that is open to that sort of investigation (some are, some aren't, unfortunately at this stage it's still rather luck-of-the-draw).

my regimen: regimens-f22/topic2489.html
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
