question: My 7 year old daughter complained of her inner leg/thigh pain, right near the groin area hurting. She said it hurts her when she presses on it or even if she doesn t. So I had her pull her pants down and I started pressing and feeling around and felt a very tiny, pebble like thing. The other side didn t have that pebble like thing. And it s underneath the skin. What can it be?
