i think i may be allergic to the sun. i know i ve never been any good at heated tempretures. however, this year i have had lots of hives on my arms, neck, legs and have. i do not eat dairy and have a low gluten diet due to tummy isues. i watch my sugar because i have type 2 diabeities. i have some food alergies and also to pollin and mold. with all those issues i can not put my finger on why my hives are sooooo bad. it s rare for me to be reacting so much. however, this year... i am stuck indoors. covering up very well when i do go out. it seems to be working so far. could it be the sun?? never had a problem with it before, then again, at the age of 15 i became lactose intolerent, could that happen to me at the age of 42??
