Hi, for about 2 months, i have been having rashes similar to mosquito bites on some particular part of my body, mainly the upper arn, back on my thigh, back, buttocks and sometimes in my lower legs. This seems to happens especially at night and very rarely during the day.The worst part is the constant itch. Initially, I thought they were allergies and took some zyrtec. This seemed to calm the itch and rashes initially. But lately, the effect of zyrtec seems negligible. I had the same problem a couple of year ago but it subsided in around 1 month (in autumn)I have been through many website and read about scabbies and other potential dermatological disorders but the systems seems to be different from what others have been describing and different from the pictures. please help.34 yr old male of indian origin living in South Africa

Hi thanks for writing here. You are having nighttime itching which is not relived by cetirizine, it may suggest scabies, but it has to be confirmed. Go through following points which will give you a clue for diagnosis. 1. See whether there is itching on your palms and soles because adult scabies never involves palms and soles.2.whether there is itching on your face, adult scabies will never involve face.3.see for lesions in genitals, in almost all cases scabies have genital involvement.4.ask other family members or household members for history of itching. From these clues you can find out whether it is scabies or not. If you have scabies then you can apply permite5% cream to whole body starting below the neck, apply entire cream in a single application, and continue with tab.Atari 10 mg at night. If you think it is not scabies then it might be allergic rash, in that case you can continue with tab.Allegra 180 mg at day, and tab.Zyrtec at night. If still no improvement then it will be better you consult a dermatologist.
