Hello there.. I am sincerely hoping u can help me out.. I have had a rash that appeared at first as a deep purple malar rash but then eventually lightened to red... and spread, throughout my face... The thing is, you can only see the majority of it when it comes into contact with water - it gets horribly red and has spread over my face over time.. It now has a small place on my neck as well.. Now, it is always slightly visible (even moreso these days) on my cheeks.. and for added info when a dermatology place that came to a health fair was checking "sun damage" underneath a UV light.. you could see the rash discoloration of my face (malar).. I dont know if it could be related but my I used to wipe my 7 mo old sons face whenever he came into contact with mine.. When I stopped, it seemed like he got a rash too.. Recently sick, he was presribed Zithromax which appears to have gotten rid or lessened the rash.. I know baby's get a lot of rashes so I dont know if it was related but I thought id mention it.. However, you could always see his rash it wasnt aggravted by water... PLS HELP! God bless!
