I've had a similar incident. My right salivary gland was swollen up like a walnut (before I was diagnosed with SJS). They did a CT scan and diagnosed the same thing--reactive lymph nodes. Only instead of a toothache, I had really bad ear pain. I am sure that it is pressing on something or the pressure is causing translated pain in that part of the face. Of course, antibiotics are going to do NADDA, so try putting hot compresses on your gland and massaging it. I wouldn't pull the tooth unless the dentist says that's it because it may not help. Just my advice. Best of luck to you!!! It is a miserable feeling--- also, feel assured that you are not crazy or just whining. This made my life miserable for a good year. Now that I am learning more about SJS, I spoke with this with my ENT. Since my diagnosis, things are starting to come together. Not that information has changed my predicament. Maybe see an ENT before you do anything!
