I have an odd, rhythmic throbbing in my right ear that has only just developed... It's fairly 'loud' and consisted of 4 short spates of 'vibration' then a very brief restbite and a long period of 'vibration', how ever it has begun to become more irregular now, in both the manner in which it is occuring, the duration of each period of 'vibrations' and the spaces between each period. I say 'vibration' as I can hear this throbbing more than actualy feel it, but there is really no other way i can describe it beyond "thrumming" and I don't even know if that's a real word....
