Got up yesterday morning with a rash on my right breast - put antibiotic cream and Benadryl on it hoping that it was something I was alergic to. Yes, it started out hurting but that has basically stopped. Since yesterday morning my back (on the right side) has been hurting, but no rash there. Got up this morning and now it is under my arm also. Called the doctor and see him tomorrow at 2. Any thoughts - does anyone think this is a flare or shingles? The rash is raised and some look like they have fluid in them. If it is shingles on long do you have it - what do they usually treat it with since we are on so much medicine. I have never had a rash with my Weg's. Any thoughts would be appreciated.
