Since 2019. After I swallowed air while taking pills. Had pain at end of esophagus for 2 days. I'm done with other half of sleep study. Afterward, I had no vibrations for over a week. Never had covid or the shot. This morning I had the vibrations from my chest to my feet while sitting in my glider. Didn't have any last night. They went away only after I got up. I use my cpap machine the minimum 4 hours right now BEFORE I go to sleep. I'm not having issues with sleep apnea because I'm dreaming every night. I see neurologist next month and discuss it with him. I'm baffled also because if Google internal vibrations and really research it, it could be anything from pre Parkinson, MS and any central nervous system ailment. I firmly believe mine is from injury to phrenic nerve. When I researched it before and got to the reasons one might have injury, swallowing a huge gulp of air was one of them but then so is coughing or sneezing too hard. That's what made me think back to a couple weeks before when I did that. My neurologist thinks I'm crazy. To me, it made sense with the cpap that having the air forced in somehow affected the diaphragm since the phrenic nerve controls the diaphragm and the diaphragm controls breathing. My neurologist thinks it's from an over active central nervous system but I had only 1 episode of CSA during my test and 5 OSA, that was WITH the cpap. Without, I had 31 episodes an hour. My machine is still set at 4, the lowest it will go. Other people have 80 plus episodes an hour so mine is very mild but obviously it's enough to give me vibrations. I'd LOVE to be part of a research to figure out what the heck is going on. Is it something environmental? Something we are ingesting? Breathing? A side affect of certain medications? Could it stem from long term use of certain meds? I'm just really surprised there isn't a doctor out there SOMEWHERE willing to take this on. Who knows, it could be a ground breaking discovery. I know for a fact it isn't in my head because too many people experience it. PLUS the fact that it moves to different parts of the body. If I'm in bed, it wakes me and the vibrations are mainly confined to torso area, pelvic and once in a while I'll feel it in the buttocks area. Sitting in my chair, it was from my torso down. I told my doctor once it feels like the blood is rushing through my body at 100 miles an hour. It is so hard to explain. I know that I'm not hallucinating when I can place my hand on my side and actually feel the vibrations. So if there is ANY doctor, medical student, I don't care at this point, I'll be a Guinea pig, that thinks they want to tackle the challenge, just let me know. I'm bewildered as are many, many others it seems.
