I have what looks like a rash, tiny red bumps, mostly on my torso. Really bad on my bra line, waist line, underwear line, and on my thighs. My skin is incredibly itchy at night time. If I break a sweat, it is really itchy under my bra. I have had this for about 3 weeks now, no treatment, since I have no idea what it is I'm dealing with. I do have eczema, but I don't think that's what this is.
