Hi I have a rash around both my armpits, it seems to be more noticeable after a bath/shower. It feels a bit rough to touch and does not have an odour. I have had this rash for around a couple of weeks. I had it last year and I put cream on it and it did go, but since then I have been tested for cholesterol which was high but I managed to get this down myself through diet only. I have been tested for diabetes and it was 6.1. I'm concerned this rash may be to do with cholesterol or diabetes. Thank you
