I have a spot on the left side closer to my butt cheek. It's like 3 inches away from any opening. It's the same color of my skin. It's about the size of a small stud earring. There is no opening on it. If i run my finger over it . . . it's hard under it! If i push it then it hurts. I have not tried to see if i could squeeze it. It doesn't hurt unless i push it. I do shave EVERYWHERE && I have a doctor's appointment next week for an STD panel. BUT i am worrying myself to death. Any ideas of what it could be possibly. Thank you!!!
