No you don't want an ingrown hair down there. They require surgery to remove and you end up with a great hole that needs packing for a week and also a hospital stay for at least a few days. Well there the ones I have seen. They are not common in women though mainly men and they are really bad. But I didn't read that bit that its between the two so I think your safe. Maybe its an infection of some type and some antibiotics will help clear it up. Definately go to the dr sounds very painful.
