Dark circle red spots on chest

[kingkhmer]

What are these dark red circular marks around my chest area. Ive had 2 just below each of my nipples months ago, it was a while back cant really remember. these marks never went away, and i didnt think anything of it until recently some of the same marks, same look, except size popped up on my skin. Im really worried, and trying to figure out what this is. There is no pain, itching or irritation with these marks at all. Please help thx.

Thanks for responding, it is summer in Minnesota, and I do sweat profusely. I work out in the sun, and i do lot of physical activity, sports, exercise, etc. Im going to see the doctor on monday. I was really worried, but if its possible these marks can go away that be great.

Hello,
From the picture and symptoms it sounds like pityriaisis versicolor. It is a common skin infection caused by the yeast Malassezia furfur. This skin disease commonly affects adolescents and young adults, especially in warm and humid climates.

Most cases of fungal infections respond to over-the-counter products, which contain any of several basic ingredients: miconazole, tolnaftate, terbinafine,ketaconazole and clotrimazole.You can consult a pharmacist and get any cream or lotion containing these ingredients. Some of them are Lamisil, Monistat derm, Mycelex, and Nizoral.
I hope that helps.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.Kind regards.
