i have a growth on my inner thigh and i dont know if i should be alarmed or if it is harmless. it just came out of nowhere and literally developed over night. its small in circumfrence but large and appears to be full of some kind of fluid. i do not shave in that particular area and there does not appear to be any hair on or around the area. its color is a flesh color around and a purple color on top. please let me know if i need to freak out and go to the dr. or just be calm and treat it some way here at home. thanks
