Thanks for you answers. I think I'll keep a food log and see if it happens again. Maybe hormone too, It was that time of the month and got hives bad 3 days in a row.
Hi I get it alot. It is a serotonin hormonal release. I actually had a great dose of red flushing whilst talking to my (then) psychiatrist. He was great and showed me the cause of it is to do with the brain releasing a serotonin rush. Doesn't make you feel good, but it just does it.
At the time I was VERY hypo and do notice it far more when I go back to hypo, like I am now.
Being fair skinned we are more prone to it too, unfortunately.
I get that when I am hypo., and also from my female hormones at times...lol
Keeping a food diary will help you to know if it is something you are eating.
