I am wondering if there is any connection between heart disease and a full,somewhat numb feeling I have around my left ear radiating down my jaw? I had a series of treatments for that ear including drugs, drops, and a tube. This all started about the same time my various heart conditions surfaced. According to the ENT doctor I saw the eardrum is fine, and time will take care of the rest. However, I continue to have this sensation in that ear with compromised hearing from it. There is not a lot of pain associated with this, just extremely annoying. Both of these conditions started a year and a half ago. Could there be a connection?
