I have a large cold sore, swollen glands in my neck and sever mouth/tooth pain. what is going on and what doctor do i see?

Your dentist: This could all be related to the "cold sore" but with what you are saying about the tooth pain. You could have multiple problems as in a cold sore affecting your swollen glands but it could be an abcessed tooth which is producing bacterial infection and possibly that is causing the glands to swell. Bottom line see your dentist.

First cold sore?: If it is the first time that you are having a cold sore then you might be experiencing primary herpetic syndrome and you should see your medical doctor to get an antiviral medication.

See a dentist: You should see your dentist for an evaluation and prescription of the right medication for your problem, the tooth pain is probably separate from the sores so that will have to be adressed as well.

Swollen Glands: Your cold sore may be infected and created a secondary bacterial infection. The viruses in the cold sore and the bacteria are probably related to the severe mouth pain and dental pain, so they are all symptoms that should be treated asap. Contact your dds first for consultation. If necessary, he may recommend that you see your md. Keep the area(s) clean!-- and make that appointment today.

Oral surgeon: Treat symptomatically. Symptoms should resolve as "cold sore" resolves. If sore persists, may be another problem. If so, see oral surgeon.

Get help ASAP: See your dentist for examination, x-rays and treatment. A tooth infection will not go away on its own. Moreover, the infection can spread so it's important not to ignore the symptoms.
