Could be restless leg syndrome, I have had that since I was a kid. I often bounce my feet continually when I am seated at the table, used to wave my legs continually in the air when I was a child. I actually was disciplined often in elementary school for not sitting like a lady- this was the sixties with ridiculously short skirts and I was an unusually, even unnaturally, tall child. ( I am 6'2").
RLS often accompanies CMT.
I only just asked my husband if it annoyed him, after more than 30 years. His "not really" was unconvincing.
