I am experiencing pain in the front of my neck on the left side. I feels very tight...like something is swollen. I can swallow and breathe ok. It started intermittent and now how increased for the last few days. I had ultrasound on thyroid..nodules on both sides..benign. Had a sinus infection in May with swollen glands..the glands are still a little swollen! I can only take Tylenol..I am on Coumidin for antiphosphalipid syndrome. I am also a diabetic. Could it be a hidden dental infection going down my neck...( I have recently been to the dentist)
