Somethings up…. on the 11th, my one ear with an eardrum was making thunking sounds in my head for about 20 minutes, today again it happened…. been happening a lot for no reason, saw doctor, they can’t explain. It except that it may be due to atmospheric pressure …. first time I’ve heard that… the ear with no ear drum..( navy related) makes a thunk noise also ….but have no hearing in that ear…
