Can stress induced clenching of the teeth and strained jaw muscles cause swollen glands in the neck?

My life became quite stressful a year ago when my newborn daughter suffered a stroke. She is fine now but I have been struggling with some painful and scary symptoms. When she was about 4 months old I had a dental filling put in. The dentist used a horrible dental dam contraption on a metal frame that really wrenched my mouth open. From that point on I have had face pain and noticed a swollen gland in my neck. I was very tense from the problems with my daughter and I notice even now that I hold my jaw tensley and sometimes clench my teeth. I believe that the stupid dental thing in my mouth injured the muscles/tendons in the tmj area and exacerbated any tension I already had in that area. Now I have alot of the typical teeth clenching/tmj symptoms such as occassional ear pain, head and neck pain and tightness down that side of my head, neck, and back, AND I still have swollen glands in my neck on that side. Has anyone else experienced swollen neck glands with TMJ and clenching?
