I've had severe allergies for years. About 5 years ago, I developed these red, painful blisters on the inside of my nose. My allergist never really gave me a direct answer when I asked him what it was. After being prescribed Nasonex and Allegra, they went away. Unfortunately, they have since returned after moving to a new climate. Muggy, humid,etc. I don't have insurance now, and I have Bipolar Disorder and take a lot of meds for that. I have been taking Claritin off and on. Has anyone else experienced these painful little nose blisters?
