The problem started at the beginning of winter. I was wearing Uniqlo thermals and my usual dove deodorant. An area around my armpits became extremely itchy and sore with eczema. GP gave me betamethasone for the eczema.
I ditched the thermals and started to use an eco deodorant. It seemed to improve for ages and the eczema has gone but my armpits become very sore and uncomfortable when I sweat.
I think it's called prickly heat.
No idea how to get to the bottom of it. Any ideas?
