I have stayed in derby,uk, for a week. just yesterday i found some rashes on my neck below both sides of my ears. they appear red and painful to touch?

Based on what you: ...describe, my concern is a skin infection. Staph & strep skin infections can cause redness, inflammation, tenderness too the touch and soreness. Unlike Zoster, a painful skin condition that is limited to one side of the body, bacterial skin infections can affect both sides. Best to see a doctor or, if you live in the U.S., a HealthTap virtual consult for this. Best wishes! Dr. Anne.
