i think the histamines may have been making my face redder- i discovered that i have an allergy to fungal and yeast spores and starting taking anti-histamines daily and my face doesnt get as red when i exercise (unless i get REALLY hot but i expect most people get a red face when they're very hot
). i also avoid all forms of wheat and wheat derivatives as i'm allergic to wheat, and i've noticed if i crack and eat some then i do get very itchy and prone to a red face when i'm warm.
i've also discovered that i have PoTS which may be influencing how red my face gets as it makes me very heat intolerant so i probably get far hotter than i realise as i dont feel it properly, until i'm absolutely boiling... but i dont get anywhere near as red as i used to get when i posted in this thread in 2008 (cant believe how fast time is going- it feels like only a few months since i posted that one and its been almost 4years!! wow!
