Hello Checker34, Congradulations on tossing the tobocco products out. I hope you can kick the habit for good.
As far as your insurance goes if you have an insurance card there should be a number to call to find out where you can go. To see a ENT Doctor you probably will need a referral from a primary care physican. You also may go see your dentist and have him check it out. He may also refer you to a ENT if needed. There are some people on this forum who may be able to tell you exactely what to do that work in the medical field. I hope it turns out to be nothing and you can refrain from any kind of tobocco usage.

Your Friend, Dan
