Temperature Change Itchy Skin Rash
(Gold Coast Queensland)
The rash I am experiencing comes and goes with changes in temperature. If the weather cools, the rash will go away but when the temperature raises the rash starts again. I have been suffering with this type of skin rash problem for five months. I have been to doctors and dermatologists. Biopsies and blood tests were done and all tests came back negative for allergies. The dermatologist had never seen a rash like mine before. I work outdoors and she suggested it was sun related and prescribed Diprosone. This medication worked at first but the rash returned a week and a half later. I continued using the Diprisone but it was not effective anymore.
The skin rash gets worse whether I am outdoors or not. If the temperature outside increases the itchiness starts up and overnight it dissipates, but in the morning as the sun comes up and the temperature starts to rise slightly, even if I am inside, I start to get itchy. Where my arms and the top of my hands are exposed to the sun I have red inflamed lines which appear after hot days. If I apply sunscreen this inflammation becomes more noticeable. I had a biopsy taken of this inflammation which returned negative.
The rash appears as small red spots and also in red rings mainly on the arms. If anyone has a similar rash it would great if they could share any way of curing or even identifying what is causing it. I am at a loss at the moment on how to rid myself of this. Any help in this matter would be appreciated.
