For a few days I ve woke up with a swollen gland under my chin, and yesterday I got a full blown cold sore. I was wondering if my cold sore could be the culprit of my swollen saliva gland. I m 39 yrs old and have had cold sores since I was a teenager and have never had my saliva gland swell at the same time.
Hello, It could be a swollen lymph node. It is due to infection or inflammation in the surrounding region as in case of decayed teeth or pharyngitis.  Consult a general practitioner and start a short course of antibiotics. Generally, it will settle in a couple of days. If symptoms persist you can consult an ENT specialist and get evaluated. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
