Deep down in my gut I know this was triggered by long Covid.

I went to Europe two weeks ago and had every type of carb you can think of, with no issues.
In context ↗ - Now: Relapsed
It’s been the worst, most painful, mentally exhausting thing I’ve ever experienced.

Summary
After COVID infections they developed chronic sinus congestion, food intolerances, gut problems and severe weight loss. An AIP/low-histamine diet and cutting gluten were the only things that relieved symptoms; antibiotics for chronic sinusitis and Claritin did not help. A severe abdominal infection brought three hospitalisations, and weight loss and food sensitivities persisted, while in 2025 PRP microneedling improved their skin.
