For months now, i've had some very odd symptoms. my entire chest/abdomen area, back, and thighs(inner/outer) feel like they're burning on the inside, even though cool to the touch. there is a 3 to 4" band around my chest that is numb to the touch?

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Wish you good health!
