<s>[INST] Hi I quit smoking 96 days ago(smoked for 4 years 3 packs a week) but had a relapse for a week and smoked one pack of cig. I had a sore throat for 3 days which has gone away but know I have pain under my jaw line. It comes and goes, Mainly just throbs for a few minuets then goes away. I didnt know if this was lymph node or thyroid problems. Should I be worred about cancer? [/INST] Hi, Thanks for writing in. If you do not have any ulcerative wound in your mouth or lumps in the neck region then there is no risk of cancer at present. A throbbing pain in the throat and jaw can be due to many reasons including sore throat due to infection. You have taken a good decision to quit smoking, but please do not start even one cigarette as it is an addiction, and you will get into the habit again. Most people have craving for smoking after few months, but you should avoid any smoking from now. For sore throat you can do gargling and this will help you to soothe the throat and get comfort. Please do salt water gargle twice daily for a week, and you should be feeling better. In case you want to completely confirm the absence of lymph nodes and thyroid problems then do an ultrasound scan of neck. Please do not worry. </s>
