Third and Final appointment with and ear nose and throat doctor

I saw my third sinus doctor for this intolerable pain..the other day  

He Told me I didn’t have sinus issues at all, but that I had Tmj. Then he tells me to go to an primary care doctor or my dentist

I had already been to the dentist several times before I saw this doctor

I already have a mouth guard in case it is Tmj

Unfortunately I am absolutely exhausted from the pain as well. The apartment has been getting dirty and I am very ashamed 😔

I am so confused. I tried again for help only again to get the runaround

My 48th birthday is also in a few days
