hi, i have been getting a rash on my chest and on my shoulders. it does not appear any were else and seems to get aggressive at night after a long shift in the kitchen. I started as a Chef last August and about 4 to 6 months ago i started to notice this rash. I went to my GP s 3 months ago and got prescribed Cetirizine Hydrochloride, and half finished the course but not regularly. Nothing has really changed, went back to GP s last week and got same pills, have been taking them as prescribed, 1 a day, and have noticed nothing! Have been pretty stressed over the last year, its been difficult.Dopnt know if its stress related or a elegiac reaction. The rash is patchy, kind off raised, not as much as a nettle sting and does not itch.
