very itchy bumps on arms, legs and lower back
I have been itching for over a month. It started as raised areas on my arm that itched. After I itched they turned red and some would get scabs (from itching). It then started happening on my thighs and has moved to shins and lower back. It itches constantly. I have been to a dermatologist and they did a biopsy, but can't tell what it is. They are trying to treat with Dapsone, but it is not helping. I did start going to a tanning bed this week which seems to be helping - I have less bumps and less itching, but they are still there. Some are now getting to be like little blisters with heads on them. I have been tanning every day, because if I go every other day, the itching is terrible again on the second day. Please help!!!!!
