My brother has had spots for a month or two now. We have been trying to treat them. They are all over his body, They seem to make him ich very often. They are big pink bloches. When he first got them It look like small insect bites, but then they got bigger. We tried vinagur in a bath and let him soke, creams, powders, so much... Is there any idea of what this is, os It is caused by? Help. GOD bless.
