I haven’t been able to wear perfume for about three weeks now because of a terrible rash that’s developed at my throat and elbows . It was caused by a well-known sleep aid that has another side-effect that’s much more common, namely sleep-walking. That I could have handled. Not being able to put any perfume in the crook of my elbows is killing me! I’ve been putting a small amount on my wrists, but they don’t hold scent nearly as well as the elbows.
