After several test I was diagnosed with TMJ. The only symptom I have is a pounding (like a heartbeat) in my ear and on my face outside of my ear. It gets worse after I chew or speak. I also have like a grinding noise when I open my mouth on that side. I don't know if this is a correct diagnoses. Everyone I have spoke with said that TMJ is usually a ringing in the ear, not a heartbeat. Has anyone experienced this from TMJ?
