If that question is for me the vibrations have been going on since 2019. I honestly believe it's from injury to phrenic nerve but using cpap machine has all but stopped them. 4 nights in a row now no vibrations. My neurologist thinks I'm crazy but it makes sense to me since the vibrations are from injury to phrenic nerve and phrenic nerve controls diaphragm and diaphragm controls breathing and having air forced into lungs with cpap somehow does something for the vibrations. I use the cpap for 4 hour BEFORE I go to bed. I slept with it at first but wanted to see if there were similar results like with sleep study, didn't have vibrations for a week and a half after 2nd half of study with the cpap.
