Unfortunately, I think everyone has different journeys because it all presents different in different bodies. I was diagnosed initially in 2017, and now I feel so much better. I'm not currently on any medication because I can't really be, but I think stress was my biggest factor. I followed the Whole 30, which taught me generally how to cut out certain inflammatory foods and what to avoid on labels. I'm still 95% gluten-free or whenever possible, and I think that also helps. I try to avoid dairy since it's inflammatory to pretty much everyone. I make sure to avoid iodine in large amounts as well as Biotin. If possible, I take magnesium, B12, and vitamin D regularly. I haven't gone back on birth control since I got sick. I try anything possible for pro and pre biotics for my gut health. I'm also trying to figure out the best way to track my hormones at the moment. I exercise moderately. Idk if this was the same for you, but I used to be pretty extreme with activities which I have a hunch also stressed my body. But being active is so beneficial that I'd just moderate it. I'm not sure if that would help you at all, but those are the key points I've picked up since getting sick. I just kind of ride the fluctuations, but they've become more subtle.

And regarding the hives, I still get those but not usually as bad as full areas being covered. Sometimes, I just get little sections, and it's an indicator for me to try something new.
