I don't know why, but usually once a day, I had a period of about 2-3 minutes where my skin on my torso(mainly my back, but my chest and stomach too, to a lesser extent)starts itching horribly. It feels like I'm being stabbed by needles everywhere on my body, and lately it's been hurting very badly, to the point to where it almost makes me cry. My mom says it's dry skin, but lotion doesn't always help. Infact it's only really helped once. Also, it seems that when I think about it, my skin starts itching again, like right now it's happening. Does anyone have any idea what this could be?
