I am 20 . Yesterday I noticed a kind of pimple on the left of my groin area which was painful when pressed just like any other pimple . But today morning when I woke up , I noticed a swelling in that area ... (It s still paining) , as I touch it and press it a bit , I feel a little stone kind of thing inside . Please help I am very worried . I preferably wear thongs and tights as I am gym freak , could that be a reason ? Also I am undergoing a laser treatment in that area and the doctors specifically warned us about not pulling out any hair strand , so I was wondering maybe the tight panty might have pulled the hair causing this swelling ? Help ?
