Tmj, Salivary glands, or what??

I've had so many medical problems that doctors say they are related to stress...I've been diagnosed with tjm. sometimes the side of my face swells and feels like it is dragging down towards my jaw my neck even swells this also happens after I eat, and sometimes when I move heavy things or even when i work out my arm goes numb on that side like I can hardly move my fingers. I have a lot of pressure on the top of my head and numbness but not much pain. My tongue goes numb and my head will tingle on both sides. I know i have tmj I've heard the popping and clicking of my jaw. But my symptoms just keep getting worse have a bump on my left rib I've heard doctors say it was rib cartage I guess out of place. Another doctor called it a fatty deposit I think. Lately I've been having problems with my bowel movements and passing gas and I've had UTI's. I've felt balance like after doing something like jogging or walking up stairs and I've been having arm cramps and leg cramps on both sides of my body. I get awful lower back pains. and sometimes it feels like my whole body is aching. I have chest pains on both sides and tingling on both sides of my chest sometimes. My shoulder blades hurt too! I've had mri of my brain and a ct! I know have more symptoms there are just so many....Does anybody have any ideas??
