Does Carvedilol, Mexilitine, Furosemide, Sotalol, Pantroprazole, Aspirin, Spironolactone Or Klor-con Cause Side Effects Of Hives?

I have some sort of allergy to one of my meds ? I was getting hives, just on my back. I stopped Spiriva, and they went away. Now, they have come back, after a month of being gone. I am on the following : Carvedilol, Mexilitine, furosemide, sotalol, pantroprazole, 81mg aspirin , spironolactone, and Klor-con. I also use albuterol inhailer. Is there a test, or a way for me to determine which is the most likely one to stop ?
