We live in Arkansas. I have been to an allergist and a dermatologist. I think it's a combination of heat and sun. Some theories are this is caused by mercury from vaccinations that I received as a child. Other one is genetics. But the swelling is bizarre
where do you live a humid state Florida is one of the worse places for lung pt and heart pt and asthma pts and allergy's find a allergist or talk to your doctor
You do not say if this swelling and redness occur when you have been outside in the sun. If so, it could be an allergic reaction to the sun. Might want to wear a hat....
If this is happening inside the house on hot days, it could be that you are dehydrated and need to drink more water, gatorade, and stay away from tea and sodas.
Something else that causes red face and swelling is diabetes or gout. Please see a doctor.
Hope this info was helpful. Wishing you the best...
