I too started having internal tremors about 2 months ago. I’m visually impaired so please excuse typos. But the really good news is mine have stopped!!!!! Ohmygosh these were scary. They were so strong I almost couldn’t sleep. I don’t know much but my doctor thought it was from nerve damage since I am a T1D (juvenile diabetic) . But I don’t think so. I had serious high blood pressure issues all year. TIA’s and just at the end of Nov 2019 I found out my brain checked out but my heart has a super high calcium score of 1,333. Should be less than 400. My brother is not diabetic and his score is considered very high too at 500. Lol mine is worrisome. But I found out then I had 3 heart blockages. Now I did recently start a very low dose anxiety med because my doc thought it could help my high be. And I do have a low thyroid all my life. But thyroid has checked out too. The very first time I felt the internal vibrations I had overdone cleaning my closet upstairs and oh I guess I’ve had the vibrations 4 months cause the first one was late September when I was cleaning my closet and I felt like I had a serious heat exhaustion. I laid down and woke with the internal vibration and also a visual disturbance in my best eye. I’m blind in one eye. But anyway. Race forward almost 4 months and I had 2 stints put in my heart 2 weeks ago. And last week these vibrations started getting less strength in the vibration. I could at least tolerate them. But now they are gone!!!! I’m sooooooo thankful I can not explain how much cause I’ve just not understood what was happening tome!!! I just looked this up again and found your forum and had to tell each of you there is hope. And I also wanted to say what my circumstances are. I’ve had blood pressure meds changed and it could have o do with that too. All the things I mentioned. Diabetes and low thyroid are both autoimmune diseases so I have both of them. Anyway ask me any questions. Sending you prayers for yours to go away🙏❤️
