Based on your symptoms of painful, tingling, and rough patches, you may be experiencing Shingles (herpes zoster) or a sun-induced skin condition like Actinic Keratosis. Because these conditions require entirely different treatments, you should see a doctor promptly for a proper diagnosis before applying any medicated ointments. If it is Shingles, prescription oral antiviral medications are most effective when started early. For temporary relief, you can apply a cool, damp compress or a plain, fragrance-free moisturizer like petroleum jelly. Please avoid self-medicating with over-the-counter steroid creams until a physician evaluates your skin.
