Can ulcers in my throat be an allergic reaction? I also have red itchy rash on my arms, and on my palms of my hands. I am thinking that I might be allergic to aspirin, which I took last night. Equally, I sometimes take Aleve as well. I never took these drugs up until about three years ago, and I have had these skin problems since. I use to used Panadol and Ibuprofen while in the UK. In Taiwan and Korea, they use mostly American drugs, if not their domestic ones.
