Few red tiny itcy bumps on skin from last few days , overall 8-10 on whole body like 2-3 on bak , 2-3 on thighs etc..they go away in 1-2 days n again appears at new place. I was assuming mosq or tiny insects bite but doesnot look like insect as noone else in family facing this problem. Currently using abzorb powder from 3 days , some improvement but still problem persist. Please suggest what can it be and solution
