This is likely a symptom of either histamine intolerance or Mast Cell Activation Syndrome (MCAS), which I have as a co-morbidity with another condition. Research around MCAS is in contention with two opposing camps, so published research is currently all over the place. For me it’s related to overactive mast cell degranulation triggering dysautonomia. Once the autonomic nervous system is dysregulated the symptom list becomes expansive. This is a pretty thorough paper on histamine intolerance specifically, and it discusses buildup of histamines in certain foods and associated symptoms. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7463562/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7463562/
