I have the same thing and it drives me absolutely insane, especially when it’s so strong that I am unable to sleep-like last night. I had the actual Covid infection in 8/2021 and was mandated by my work to take the vaccine 12/2022. I am not sure if the vibrations started after the virus or if it was after the vaccine because for months I thought it was external and would lay awake at night trying to figure out what was vibrating! At first, I thought maybe it was our Sleep Number bed because it tracks your heart rate and your breathing and it also has several huge magnets that hold the mattress on the frame. Later when I slept away from home, I still had them-so not the bed! Finally I read on a long Covid facebook group post someone mentioned “internal vibrations” and I was like “OMG! This is what it is!!” I can’t believe that I never suspected that it was part of my LC! Thinking back, after the Covid infection, my worst symptoms were cognitive impairments, fatigue and shortness of breath and I was on supplemental oxygen for 3 months afterwards until I weaned myself off. The shortness of breath is gone but I still have cognitive issues and fatigue very easily after I do any physical or mentally difficult tasks. I forget what I am saying half way through telling a story or I am unable to follow stories other people tell me. I have trouble finding words that I did not have prior to Covid. I walk into a room and forget why I went-especially if someone distracts me by asking a question. I have been an avid reader all my life. I started reading when I was 3 years old-my mother did not teach me-no one taught me-my mom said that when I was 3, she realized that I could read. I remember a family member visiting and my mom was telling them that I could read already and the family member said “oh! she is not reading, she just knows her books by heart!” So he tried pointing out individual words and I read them right every single time so he finally agreed that yes, I could read! I was always reading some book every day but I haven’t been able to read more than a few pages since Covid because I have to keep rereading because I can’t focus on it. This more than anything tells me something happened to my brain when I had this virus. I saw a neurologist and they did a bunch of expensive tests and said my memory is “normal for my age”. This is not MY normal!! I think next time I see my primary, I will ask her to refer me to a different neurologist for a second opinion. I don’t believe that I mentioned the vibrations to the neurologist though. I think that the internal vibrations started after the vaccine-along with weird rashes and hives. I have photos of some of the rashes especially the great big itching burning hives-huge wheals that would pop up randomly for about 2 years but for now, I haven’t had the rashes in a while. This stupid virus and that vaccine really screwed me up and, of course, the government is off scot free for poisoning people! Stress definitely makes the vibrations worse and if I eat too much sugar they get worse. I really wish I could find something that helps.
