Hi Jo, I started having internal vibrations that seem to have started after I had covid infection. In 2022 it started about 2 months after the infection and I mistook it for heart palpitaions. I saw a,cardiologist who said there was nothing wrong with my heart and the palpitations stopped a few months later. In 2023 I cad two covid infections. After the 2nd infection in May, I developed long covid and was extremely fatigued for several months. By October I was feeling about right, and then my sister passed away very suddenly. This set me back healthwise. I have type2 diabetes, but it hS bee reasonably well controlled for many years. But now I find I have these internal vibrations a lot of the time, through my core and in my legs, hands and feet. I have not had any diabetic neuropathy before, but have thought that these internal vibrations may be that. They are usually worse at night when I lie down. I often eat a biscuit or a piece of chocolate at night, so it is possible it is the sugar in these that trigger it. I have not taken any medications for it - I'd prefer to know the cause first.
