Help! I Have a Question About my Health!?

Heat rash maybe? Sitting at your computer too long and with feet up so your tail bone is contacting chair for extended periods? It sounds like either heat rash or a contact dermatitis (allergic reaction to something touching it) and you have scratched until it is bleeding, and the clear is also from you scratching too much. Try keeping the area dry with a medicated powder and stop scratching!
