Hi. I've been chewing and dipping tobacco for a long time, and for a few days I've been having a pain, although small, but progressively getting worse in my jaw, actually inside my cheek, on the side where I chew the most. There are no lesions or swellings, just the pain for now. I'm terrified of jaw/mouth cancer. Should I go to the doctor to have it examined, or wait for a few days? My teeth are rather healthy and I just have a little bit of receding gum where I chew.
