It sounds like food allergies and/or seborrheic dermatitis.
Sorry about the misspelled words but eat is Ear,I have thought about food allergies but the rash on my chest does come up more often when I'm under stress more, the other thing going on now I do see a Lil blister like bump in my ear area, its just the bumps on my scalp I can't see and it is all staying on left side of scalp down to my ear, I'm worried about it going into my ear as I read out can cause deafness.
Herpes Zoster as it looks like, needs to be treated with oral Acyclovir ( if the diagnosis is confirmed), at the earliest to prevent post herpetic neuralgia.
I also have had a severe foot problem for 9 months now, was told plantar fasciaitis, its heal lain that's awful. My concern now its maybe I already had shingles once and did not realize out and that's why I have thus heal pain that won't go away, been to physical therapy and there is no change :( maybe I have nerve damage and the shingles have came back again. I do live a somewhat stressful life that I know isn't much help.
Was it the same area you had Zoster earlier? Most unlikely to have recurrence in herpes.
No not the same Area, my heals still hurt everyday, now I have a rash like bumps around my ear and on the scalp, when I touch the rash area it hurts bad and it burns on and off. Concerned if the heel problem may be related to the scalp rash now like both ends of my nerves in the body. Has anyone here experienced anything similar to my problems?
