What type of doctor should I see: dermatologist or regular?

I recently noticed a bump underneath my chin. There is no protusion. Perhaps it's a swollen lymph node? I've also been having a lot of acne lately and I've read that acne may also cause such a bump. What kind of doctor should I see: a dernatologist, my regular doctor, or some other kind?|||go to a regular doctor first they will recommend dermatologist if necessary |||regular doctor first and if need be he can refer you.
