Suggest Treatment For Itching Sensation In The Vaginal Area

I have a boil near on my inner thigh..Also it s seems some kind of infection near my vagina area as the area has become dark n itching is there sometimes. My main concern was the boil is twice bigger than pimple...A little hard n fluid comes out as I can stain on my inner wear. It was small initially but had grown in size now n decreases if I give warm compression or press to take out fluids inside it. But it s painful if I press it.
