Has anyone experienced internal vibrations?

I started having the only way I can explain it is internal vibrations. I've had them for 3 months now, I went to t hihe ER and they told me it was anxiety. A doctor diagnosed me at a clinic as having Lyme disease I've started a 21-day prescription of Doxycycline I'm on day 7. I went to a psychiatrist a week ago to get something because of my nerves are just over the brink. He prescribed me Gabapentin and Valium I've only been on them a few days.
Has anyone experienced these internal vibrations?I have them almost 24/7 chest neck stomach from the hips down. I have more lab tests that should be in today, but the doctor's office said that they would not call unless there was some abnormality in the lab work.
