I had several very weird months, during which I had a constant buzz in my head, along with vertigo/dizziness. I also had this weird thing where it felt like somebody stuck a giant vibrating Q-tip in my ear. All of a sudden, it felt numb, yet warm and fuzzy, and it buzzed - it was this buzz that filled my entire head and made it impossible to think.
You say that you don't have this problem on the phone? I had the weirdest thing happen to me - I kept having this problem where I'd be talking on the phone, and I'd lose my train of thought. It was worse than that - I would lose it to the point where it felt like the person that was having that conversation wasn't me. I think it must have had something to do with the lesions in my corpus callossum.
I also get a weird scalp buzz that feels like bugs crawling on me.
Hi Kerri- What a crazy world huh! Well, I can say that whatever is going on with me, I share in your electrical experiences. The other morning I woke and it felt as if my head was vibrating. I have constant random buzzing feelings. Here is one of the great Health Pages that sheds light on buzzy feelings:
