Has anyone had Middle Ear Myoclonus and how do you deal with it?

Since I had an ear infection and then perforated ear drum i have noticed i have beats in my left ear. I initially thought this was Pulsatile Tinnitus but then I noticed that the beats were not in-sync with my pulse and usually every 15-30seconds so looked to explore other possibilities.

One possibility which quickly became apparent was Middle Ear Myoclonus where your ear contracts and can go into spasm in response to certain sounds, actions or movements. This can occur for me in the mornings when I move awkwardly upon waking although more recently it has occurred due to burping or yawning and sometimes in response to loud high pitched sounds. These beats in my ear can then last for several hours and its hard to pinpoint what causes them to finally stop. I had a long period of 3 weeks since this last bothered me but it seems to have started up again.

I wondered if anyone else has experienced this and how you managed to deal with it? I've tried Magnesium supplements and Valerian tablets with some success but hoped there would be a more permanent cure?
