Question: I have been getting a rash of blisters on my back, arms, and legs, but topical treatments don’t seem to help. What can be causing this?
Dr. Hibberd’s answer:
Blisters on your back, arms, and legs probably warrant a physical evaluation by your physician. The absence of them on your chest, abdomen, or face is a clue. Presuming you lay on your back to sleep, you might consider whether you may be reacting to your bed sheets.
"Sheetitis" is common in hospitalized patients from the starch in the sheets. It's also possible you’re having a reaction to your laundry detergent or fabric softener. Wash your sheets with Neutrogena instead of your regular detergent and fabric softener, and see your doctor in the meantime for an evaluation.
He or she can determine whether a topical cortisone cream is advisable or whether further evaluation or even a skin biopsy is advisable.
