Hey Analog6, thanks for the help and input! I tried the gluten-free thing for about 7 weeks, though that was before I was savvy to the fact that gluten can be in things like tea and can cross-contaminate pans and such, so I may have accidentally ingested small amounts during that time. I'd like to try it again, but I work at a bakery and am in constant contact with glutenous substances- flour, breads, etc. I don't eat any gluten, but I'm sure I touch and inhale it. I'll give it a shot again as soon as I can get myself a new job! But I think it's more of a gut dysbiosis issue caused by antibiotics than true gluten intolerance.
Glad to hear that PB fixed your migraines/hair/nails! I'm sure you'll notice even more benefits as time goes on.
I have to gush about my doctor right now, because he is seriously awesome. After dealing with so many useless docs, the fact that this one actually listens and has lots of ideas on what to do is amazing. I went to see him this morning to follow up on all of the tests I had done. He explained that my T3 was low, and that given my symptoms, my thyroid was probably not converting T4 to T3 very well. He said that sometimes the thyroid gets "stuck" in a depressed state due to stress or illness, and once the stress passes it doesn't switch back to normal; the depressed state becomes the new baseline for function. So what he does is give low dose Armour to give the thyroid a little boost, giving the body the support it needs to heal whatever is causing the issue in the first place, and once the patient is feeling better for a while, he weans them off the medication. I should have a prescription for Armour waiting to be picked up later today.
Also, he ordered a stool culture, stool o & p with GIardia, C. Diff, and Cryptosporidiosis tests before I try the CDSA, as these are covered by insurance while the CDSA would cost mucho dinero that I don't have-o. He also referred me to a GI doc to get a second opinion on the GI stuff, possibly an upper endoscopy to check for inflammation and other things, so I'm going to make an appointment with her as soon as the referral goes through. My doc agreed that the constant gurgling makes it seem like some sort of problem with gut flora, so I think we're on the right track.
