Hi KJ,
Sorry but I can't say I have this problem, I do have allergies, but no know food allergies. I thought for years that it was ragweed that caused my allergies as the timeline for this was spot on, but after going through the scratch test at the allergist, found it was indoor and outdoor mold instead. It seems as though you are finding out the hard way what you are intolerant to. Perhaps an allergist, or a specialist with food allergies could be of help to you.
In nearly every definitions of fibromyalgia I have ever read, it is not considered an inflammatory condition, though many have food sensitivities, food allergies, and chemical sensitivities.
I do know that many of our members have found relief from an anti-inflammatory diet, and I'm in the 'whatever works club', but it doesn't sound very beneficial to you so far. Please be very careful!
Though I am not a Doctor, I have Psoriatic arthritis that is an inflammatory autoimmune disease, I went on an anti-inflammatory diet for about a year with no real results. Years later, I talked to my Rheumatologist about possibly repeating this and asked his thoughts on the matter, he responded by telling me that unless there are food allergies, that with the amount of inflammation this disease puts out, the difference an anti-inflammatory diet would make would be a drop of water in a swimming pool. He is not only a practicing Rheumatologist, but also a University Professor.
I hope that you can get to a good place with what works for you, without any additional suffering!
Wishing you well,
SK
