Ok ladies i know this might seem silly but i need to ask before i start freaking myself out!

A couple of weeks ago i noticed my c/s scar was infected- (TMI) i got admitted to hospital over night as the infection was pretty bad, got give antibiotics you know the deal anyway.... i just go to have a shower and notice half my stomach is BLUE!!! I dont know what it could possibly be? Then in random little areas i have pimple like things. I dont know if the blue is possible bruising or if it would be off my clothes i havent worn anything BLUE in weeks!
My back is aching,the right side of my stomach is cramping,and my c/s scar seems to be risen and extremly red.

Does anyone know what it could be?
