Hi anned! I'd love to know also as a few other here, what you are taking that helped? Was it the Claritin and Zyrtec twice a day? I'm starting to lose it mentally and physically. It's been 1 1/2 years since this shortness of breath started. I've have every test imaginable, 3 specialists give up on me and tell me they have no idea and go to the Mayo clinic. I can't afford to go there, and it's ridiculous that doctors aren't will to help their patients and we're disposable. ugh! I'm so frustrated and in pain every day. Sorry for venting, it's just so darn tough to live like this daily and not get the time of day from doctors.
