hi i have had severe itching for the past 2 weeks at various body parts i.e. armpit, back of the neck, groin and bum. it started off as just minor itch under the armpit area and was very itchy, when scratched it formed red spots (i can feel the spots when i touch the itch area) the more i scratch, the more red spots formed and the itch got more intense and prompted me to scratch more. now it has spread to the back of my neck, groin and bum area. The itch comes and go, but when i touch the affected areas, they will start to itch again. i need help to stop this itch and also to find out if it's something very serious.
