hi there, my name is adrian. i'm 32 and weigh about 80kg.. i've gone to australia for some military training and had to lie down on the ground for a couple of nights. after which i thought i had some fly bites as some reddish,pimple-like spots appears on my hands, arms and calves. Surprisingly, after i've been back for a month, the spots still itches. But the funny thing is, it comes on and off. Do i have scabies?
