I have heat rashes under my breast 5days ago and have treated it, but i have been noticing something like eczema on the surface of my breast area.help?

Needs exam: Eczema is certainly a possibility. A fungal rash is the most likely. If the rash is not responding to your treatment then an exam by a doctor is needed. The diagnosis needs to be made so that the appropriate medication is prescribed. You could use HEALTHTAP prime if you do not have immediate access to a doctor.

Check diet: Many times skin conditions are related to diet intake. Eliminate dairy and gluten and see if that doesnt make a difference. You can try coconut oil, shea butter or whatever lotion you like (non perfumed). If it is spreading and bothers you, be seen and have it looked at.
