I am also getting these heat
rashes in the manner similar to the post of the gentleman above. I would like to add some more details to my situation
so that you could narrow down your diagnosis.
I understand that heat rashes come
as small boils as the sweat pores are blocked and as the sweat tries to come
out at the hair follicle. When there is no place for the sweat to come
out, we get the rashes i.e., boils (the skin looks like I have chicken pox). Hope I have got this right.
