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 itchy
bumps 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.
