For about 3 weeks now I've been getting very itchy bumps on my arms, legs, stomach, back(sometimes) innerthigs, they get on my hands sometimes. At first it was just when I went to bed but now there everywheres. I went to the dr. he gave me some meds. But the second they were all used it came back a little worse. I'm 15. Can any one please help me ? The itching gets to where I can't handle it.?
