Day I had mammogram had intense itching  on left side. Blister developed and then more red itchy spots. 3 days later I was diagnosed with shingles. Has been a month. No pain, but rash spread to stomach and hairline. Itchy but does not look like shingles. Took acyclovir for a week after diagnosis. Still getting some red spots, but no blisters. Could this have been some kind of reaction to radiation?
Hi, Herpes zoster can occur after any change in immune status. You can get it after radiation too as it can lower down the immunity temporarily. Acyclovir is the appropriate medicine and give cessation of newly forming lesion. Do not worry, the redness can persist longer. You can take paracetamol tablet by mouth for two time day.
