Baron,
This is all great advice. Just put one foot in front of the other and do the next right thing. If that "sore" (which needn't hurt to be serious) is still there after 2 weeks, don't dally and get an excisional biopsy. That's the only way you'll know what it is. I hope that this is nothing.
It's never too late to stop smoking...never! Good luck and take care of your health.
Best regards,
Kerri
