I have been dealing with right jaw pain under the ear lobe , pain in the jaw line end area and neck pain for 15 months now. Not the whole neck, just the vertical line below the ear to shoulder.   Have seen many dentists and doctors. No definite diagnosis and relief yet. Checked for TMJD and have been told it's Myofascial pain dysfunction. OMFS sent me to TMJ MRI. The MRI report was normal except one incident finding. It says incidental finding of possible small right sigmoid bulb venous diverticulum. Asked the OMFS and he said he don't know about it. Don't know whom to see further. Is this incidental finding something serious or normal? I do have right ear ringing since this started. It's like mild buzzing and hissing sound. But I hear the heart beat when I lay down on the pillow on left side. It's like throbbing heart beat sent it subsides after few minutes to minimal sound. Couldn't hear it on the right. is this normal? I have high BP( 118-135/83-95). taking losartan.
