Dr Bernadette Carr answers your questions on prickly heat rash and nail abnormalities

I am a woman in my 40s and last year on holidays I got a rash on my neck. I think it was prickly heat. I will be going away in a couple of weeks and wonder if you have any suggestions?

Prickly heat rash can be very uncomfortable and I can understand your wanting to avoid a repeat.

Also known as miliaria rubra, it’s a common skin condition that occurs in some people when they sweat more than usual and the sweat glands become blocked.
