I have been chewing tobacco for probably 5 years now pretty regularly, terrible habit, I know. I've put it down for the past two weeks because I'm starting to get nervous a little. The biggest problem I face everyday is hardly being able to swallow. I can hardly swallow my own spit and it takes a lot more effort to swallow food, and even liquids. My jaw has on and off pain, and my sinuses are always clogged. Feels like I have to just pick my nose to finally clear the airway but never fully does, comes with a pulsing pain too. I get headaches quite often, maybe 4 days a week as well. Any ideas as to what's going on? Thanks for the hlp
