I am hearing the heart beat on my ear while laying down on the left side. It was there for a while and subsides after an hour or so. I noticed this recently. Is this pulsatile tinitus? I am dealing with jaw pain under ear lobe and neck for 1.5 years. Constant sore pain in jaw under ear and side of neck(from under ear to shoulder). Seen ENT, OMFS, neurologist, TMJ specialist. Taken CT and MRI of jaw and neck. Normal. ENT told me to get CT to check for eagles syndrome. Report says styloids are shorter and calcification of stylohyoid ligaments. I do have ringing in my ear often. But I could hear the heartbeat only when I lay down on my sides. Is this normal or anything related with jaw and neck pain?
