I have those internal vibrations post Covid vaccines. Have not had Covid to my knowledge. Tinnitis worse than ever was. Numbness in hands and Essential Tremor when working on small motor skills: sewing, weaving. My PT person believes I am also a long covid patient. Have some cardiac palpitations, exhausted, not sleeping well and short of breath at times. Am having MRI next week to address headache over left eye and zinging headache over left ear.
