Yes, this is one of the symptoms I am really suffering from too, but 24/7. It's debilitating. PET usually happens after long term ETD and sinus problems. Mine happened immediately after an ear surgery which I'm still trying get help for. Do you get a roaring type of tinnitus sound, gloomps/thumps? The constant roaring is what's most debilitating for me at this time.

Do you feel like your voice is too loud when you talk, making you feel off balance at times?
More research point out many patients have history of sinus inflammation - no surprise. In the past, they thought weight loss. Hormones do play a factor to both ETD and PET. I personally feel Vasculitis inflammation is one... it makes sense but nothing has been said about that yet. -H.
