A month ago, I got these little red
dots on my back and stomach. they're really itchy. suddenly, they've transferred
into my arms and legs. after sometime they're gone, my skin became "chicken skin". and now when I feel itchy and scratched my legs, red
will appear. They're like mosquito bites
. But when I stop scratching, they will be gone after few minutes. what
could these be? I have been to dermatologist, she gave me ointment and oral med, but still they're not gone.
