I had about a 2 year span during which I was taking
Benadryl 4-5 times every single day.I had a horrible time,breaking out in hives constantly.It even cost me one job because I was at the ER in anaphlactic shock.I really never found the cause but had allergy testing and they said I was allergic to 21 foods.I also reacted to just about any drug I took.Personally,I think it was my immune system gone whacko because not long after I was diagnosed with breast cancer.Now I have no allergies whatsoever lol.But I have joint pain so severe that my Dr is thinking RA.So I will definently mention the connection to my Dr.
