I came out with hives when I last took ibuprofen. I can tolerate aspirin (if that information help at all). My doctor has now proscribed naproxen for my frozen shoulder. My doctor (and the pharmacist) is aware of my allergy to ibuprofen, but said that it could be just ibuprofen or the whole NSAIDs family; and until I try it no-one will know if I will react the same with Naproxen. Should I try it (probably best in my work place in case I react badly to it perhaps)?
