I have an issue, a white patch on the left upper rear of my mouth, concentrated headache/numb patches on the left side of my face, and I've been using chewing tobacco for about 4 years (mainly chewed on the lower right corner of the mouth). I just quit a month ago but I'm noticing these issues pop up and it's beginning to scare me a bit.

It's the weekend here, my doctor is out. I haven't seen the dentist in years due to how hard the economy has hit me (like a ton of bricks)/lack of insurance.

I should get checked out soon I know... I'm hoping tomorrow I can get in. Where should I go first? Doctor, or dentist? This is out of pocket for me so I want to try and figure out where I can get answers ASAP without blowing a college loan payment/my savings account away.
