I’ve had these internal vibrations since 2/21. They start with numbness in my feet and a blood rushing sensation in my calves that work its way up the rest of my body. I started getting weird headaches especially behind my eye and electrical sensations after Covid round 2.. Sometimes it helps to walk because it masks vibrations, and feels like it’s burning off extra adrenaline or energy in my system. No one has been able to help me. I’ve seen many doctors, had many tests, and tried many medications. I will say that a recent MRA revealed a brain aneurysm. I believe it is from the vibrations. I also was diagnosed with two heart aneurysms. Heart racing was my first sign of Covid each time that led to me getting tested. All of my MRIs and CT scans came back normal, but they only check the bone/tissues. It’s important to know that you need an MRA or a CTA to check the blood vessels.
