For 3 weeks now I have been kept from sleeping due to continuous episodes of percussive thumps in my ear — 7 – 12 times in a row in an arrhythmic volley. After this sequence, it will pause for about 30 sec. and then resume. This is NOT associated with heartbeat. I can feel the vibration when I put my little finger in my ear. No change in head or body position – even trying to sleep sitting up – will stop it. No luck with massaging muscles around ear, pulling on ear lobes, cartilage, inserting an earplug deep in canal. My sleep dr. says my CPAP pressure is too low to cause this. Sometimes during day it will occur but not incessantly as at night. Will schedule ENT appt. tmw. Any insights? Thx.
