I was wondering if anyone could help me on this topic, or if someone has experienced the same. I get this rash when spearing in my suit and its only on my upper body ie shoulders, head and Face and its all like little inflamed pimples which are very painfull, and take like three weeks to dissapear, is there anything I could apply before diving, as I have tried various creams and nothing seems to work it allmost like a heat rash.
