Well Cats102,
It is NOT a worm. It is just a black head(pimple). Usually when you squeeze them they would come out long and would have a little bit of white goop at the end as well as the appearance of it becoming white/yellow color when you squeeze it out. Some teens usually get these black heads near the inner thighs due to a lack of sanitation. Well this would usually occur if you are a bit overweight or obese.(no offense) But if you are physically fit then you should notify a doctor for further details. If you are overweight/obese then you should still notify a doctor regardless of the situation. The doctor would most likely prescribe a type of cream/ointment for you to apply to your inner thigh. If you are a bit overweight/obese and start seeing more and more black heads and go to the doctors once more, the doctor would assist your parents in a patterned schedule to keep you fit and so you won't see the black heads again.
Good Luck with your situation and I hope all goes well!
Get to the hospital NOW!!!!
sweety your ok. Breathe. That is probably an ingrown hair that's built up a lot of dead skin and bacteria - similar to a pimple. Well more like a black head. There is probably a little hair stuck under the skin there. Don't continue to pick at it or you'll find it gets red and irritated quickly.
