I have everything that you do including the lump in the throat, kinda like I'm being strangled especially when I lie down. The internal vibrations are the worst for me. I literally can barely function with them. You didn't mention insomniac which was my first clue that something was wrong. But it wasn't long before the lump in the throat and the internal tremors were contributing to my not sleeping. I've been to 6 Drs in 5 months for this and I'm suppose to see a neurologist next but they haven't even called to refer me yet. Might I add that I've lost faith in most Drs since all this started for me. Seems nowadays if they can't relate to what you are saying they just dismiss you as crazy. Truth be told this condition, whatever it is has made me not want to live anymore if I have to live with the internal vibrations. Mine are worst in my chest, stomach and basically my whole trunk. I'm also experiencing massive muscle spasms in my back and my arms and hands along with all this insanity. Has your sleep been affected? Hoping you are on the mend.
