Thanks for the info -- this is really helpful! I try to eat a healthy diet, but because I also have SIBO, I have to be careful with fiber. Otherwise, I'm in the bathroom multiple times a day. I do make sure I have fruit and vegetables every day, but I have to cook the vegetables, and there are only certain fruits I can eat -- e.g. berries, grapes, Clementines. I've also cut red meat and processed foods from my diet, and only eat chicken, turkey and fish. I do eat quite a lot of rice and pasta (gluten-free), which probably isn't great, and I also eat dairy (lactose-free apart from cheese, which I seem to be able to tolerate well).

I find it interesting how many people developed PMR for the first time after receiving the Covid vaccine, or from having a bout of Covid. I'm pretty sure this is what happened to me too. My symptoms started a few weeks after my last Covid booster.
