Hi, I have a persistent localized and Dime-Sized rash along my T-4 spine area; it used to appear in the winter, now year round. It itches and flares up at night and morning. I ve used topical, OTC and Rx ointments and lotions, yet, persists. What causes it and is there treatment? RXs, Include- Lotrimin;Aquaphor; Desitin; Lamisil; EpiCeram and DESONIDE LOTION 0.05%. Can you help? Thanks, Lance
