I'll start off by saying I smoked at least once a day before this all happened.The pain under my jaw started in October and gradually got worse and worse until I finally went to the doctor in late December. It would hurt worse after every smoke session. He said it was a swollen lymph node and gave me two medications: Naproxen (anti-inflammatory) and Cephalexin (antibiotic). I started taking those and it helped a lot but when I was out of meds, I could still feel a slight pain. It was 90% better though. I did not smoke the whole month of January. In February I began smoking again and throughout the month the same pain was coming back stronger and stronger after every smoke session again. The pain isn't just when I smoke though; it's all day. It has ruined smoking for me and made me really stressed out. Has this happened to any of you guys?
