Itchy Rash on Breasts, Arm, and Thigh
About five months ago during the summer time, I developed a very small area of red, itchy bumps on the top middle part of my left breast. It was not too bad at first, so I ignored it, thinking it would go away. However, over time, the skin rash became more and more itchy, incessantly itchy, and it covered the area over the whole top, middle, and underside of my breast. Then it spread to my right breast, middle area between and the underside. It then developed in the crease of my left elbow.
Now this may be possibly unrelated, but one night two to three months later, I broke out in full body hives. I then went to the emergency department and was given three or four days of Prednisone pills and was told to take Benadryl as needed for the itching. The skin hives settled down and I determined that the hives were likely caused by laundry detergent since I had recently bought a new type. The rash and hives would go away after the Prednisone dose, but my feet ended up covered again after wearing socks washed in the new detergent. I thought it was all tied together but I guess not.
I finished the course of medications I was prescribed by the doctor and the hives actually went away and the rash I had was also completely gone for about a week. This was a great relief. Unfortunately, the relief did not last long, because the rash then came back again to all the areas it had previously been – my breasts and left elbow crease. The skin rash then spread to other areas of my skin such as my outer left thigh. This condition is so itchy that I sometimes scratch it until it bleeds. Hydrocortisone cream does help very briefly, but the rash stays and it does not go away. I have found that Calmoseptine ointment helps when it coats the affected skin areas, but again, the rash does not actually go away. Benadryl does nothing. It is reddened and again, very itchy, but is not always raised until I start the scratching. The more I scratch the more it spreads, but I stop scratching and it recedes back to those same areas that were originally affected. It is worst at night when I remove my bra, and this happens to my skin no matter what type of bra I wear. For a description of what the rash looks like, I have read it looks like a heat rash, but I'm actually always cold and now it's winter, 30's and 40's Fahrenheit outside. I am at a loss as to what this skin problem is and how it can be cure. Any comments would be appreciated.
