I have gotten a lot of vibration sensations also, though lately everything has been quiet, and I've always thought it was because the vibration fibers are hit more with with length-dependent axonal neuropathies, than with the painful small fiber neuropathies. So I figured it was a blessing, to have more vibrating than pain. Sometimes I feel it in my body, especially in the morning, deep in my solar plexus. Strange, indeed.
