Hi everyone-I haven't checked any of the responses in so long and have now read them all. Thank you so much for sharing. My update is that I began to think of the internal vibrations as a part of the healing process (suggested above by our admin Colleen). THANK YOU COLLEEN!! It, at the least, kept me from a loop of catastrophizing and allowed some space for what became full-body "thrumming" since December 2021. It lasted one year. With the help of Internal Family Systems and trauma work, meditation, continuing to watch all inflammation (I take high-grade supplements for inflammation every day and occasionally Celebrex), intuitive movement and something I have come to call Intuitive Tactile Waking (basically waking my body up by self-massage at a very quiet and calm pace), the thrumming aka Internal Vibrations just stopped one day in December 2022. It was suddenly so quiet. I had no idea that it was so internally loud with them. I think I needed to wake up my body due to disassociation from Long Covid for 2 1/2 years and the intuitive movement (not just your regular prescribed PT and performative gym stuff) helped me heal. That was my last long covid symptom. I have hope! I wish everyone continued patience and healing on their path. I will say that my functional doctor was absolutely KEY to all this and my meditation teacher gave me a workable set of tools that changed my life. Stay curious on this difficult path. Much love and support
