Pain when I eat in teeth and burning gums.

I am getting pain in my teeth and gums when and after I eat. I have never had pain in my teeth or gums at all. I have a decayed tooth but it has never hurt. All of sudden about 2-3 weeks ago I start getting a weird pain in my teeth, it's like a dull or blunt severe pain in the decayed tooth when I am eating and bite down on it. Also a bad burning in my gums while I am eating and about 1 hour after.

Your gums are burning because you're probably not flossing enough.  Flossing removes the germs from in between your gums which can cause your gums to burn.

You better go to the dentist for that tooth.  The decay might be at your root.
