i have had a ras on my abdominal area for about 2 months,its in clusters and it itches so bad iv been scaring my self froms scratching that i bleed and have small round pock marks.it started on my right side(abs) went away,spread to my lower abdominal area still there but not as bad as before but now i have it on my left flank and  and  right above my left buttock- lower back in an area of about four inches large. i cant take the itch, the more i scratch the worse the itch gets.
