2 allergists told me to take aspirin for my chronic pain even tho they cause hives. They said my reactions were non life threatening. Is this reallyok?

Odd? I agree with dr. Krauser. I am wondering if there could have been a misunderstanding. If you get hives when you take Aspirin that is a problem. You might want to double check the recommendations made by the physicians.
That is absurd. Is you have a true Aspirin allergy you should avoid a Aspirin and all nsaids. The next allergic reaction could be much more serious.
