Have Fatigue, Stiff Jaw, Inflammation On Chest And Redness In Throat. Is This Sleep Apnea Or Acid Reflux?

So for a while now i would go to sleep and weak up with weak arms, fatigue, weak legs, and shoulds; I would feel restless and my jaw is stiff. Now the stiff jaw is recent so it might be related to not breathing my teeth (Very lazy but busy person, I forget or i come home and just sleep). I went to the doctor and ask for a test to clincal prove thst i have sleep apnea but my doctor wasn't that concerned about it. I told him that i didn't breathe at night but he seemed more interested in the inflammation of my chest all over and the redness in the back of my throat. He connected that with a heart burn and gastric reflex and told me to watch my food consumptions. I want to be a doctor not a dietian so im completely oblivious to the types of food I need to consume to reduce my acidic build up. Anyways, yeah I wake up feeling weak and my jaw is stiff and hurts, i feel as tired as i went to sleep on, my vision when i wake up is like im not paying attention to things just blanking out. Which i do space out a lot but i have no known learning disabilities (no adhd or add). Could ypu please help with my smyptoms and tell me what i shold do to get bette? Oh btw I'm 16 year old black male, with a historu of heart problems in my family (uncle, grandma, and cousin), im active, might be depressed, kinf of stressed, and always hungry :) anyways please repley at your earilest convience. Thank you for your time.
