Hello, I too have had that strange feeling of head buzzing, thumping feelings etc. I was diagnosed with Eustation Tube dysfunction so I was told by my ENT that could have something 2 do with it..Haven't had any of that if late tho, so just not sure. I do get like wave sensations in my head, and am Keepin a journal 2 c what I eat when it happens. So far it seems when i eat bread it happens more...so still in experimenting stage..Hope u find answers..
