I get red hot to the touch blotches on my face, ears, chest and upper arms more so on the left side of my body anytime I get upset, drink alcohol, shower and often after I eat. I used to only get this when I drank alcohol and now it seems to be happening almost every day and I do not know what the trigger is. What is causing this and is there anything that I can do to reduce/elimate these symptoms? The only Rx I take is Beyaz birth control and I have been taking 3 Equate (walmart brand) non-drowsy benedryl every day for about a month in effort to reduce my symptoms. I am 26 y/o white female 5 3 and weigh about 145 if that makes a difference. Also, I have occasionally checked my BP during the event and it is within normal range. Please advise.
