Hyperactive Salivary Glands? Acne-like Symptoms..

I've noticed these acne-like symptoms for a couple years now, but always just assumed it was acne. Sore, red bumps form near and below ears, around throat, and sometimes on middle of cheeks... Often accompanied by a "thick" swallow.

I'm convinced it has something to do with hyperactive salivary glands, but am unsure if it is common or if there is anything I can do about it.

I have determined that these particular glands are in the general area of concern: submaxillary and parotid glands. Any ideas?

Please help, or direct me to someone who can.

Thank you.
