i am 31 years old n 5 foot 8 inches , 168lbs , i have a lump on my neck , around the front right next to my adam s apple , that seems to have formed overnight (at least i didn t feel it yesterday ) it kind of hurts , as if my skin is stretched , i have tried squeezing it and after much force only a little oily substance comes out , should i be worried ? at first i thought it was an ingrown hair , but after squeezing it , and nothing , i am worrying .
