hi - my under arms started itching about a month and half ago, now the upper part of my chest above my breasts (& still under my arms) itches and it feels like its under the skin, It burns and itches. Now the surface is bumpy but these bumps are under the skin upper chest. the itching and burning under skin is what im worried about..i thought at first i had allergies to grass because that has been bad, but this is more like an allergic reaction but now has gone on for 2 months. Or it could be something wrong - i have never had this before.
