I’m sorry. I know these internal tremors all too well since nov 2019. They did start when I was finding out about all my heart blockages. I had 2 stints places in December 2019. And they reduced in severity but were still pretty strong. I had my last stint placed in yesterday March 6. And they immediately reduced in severity. Not gone but really almost. My left foot has the worse pulse and that where I have most of the internal tremors since yesterday. I have juvenile diabetes 34 years. A low thyroid condition but the TSH they have ran although indicates to lower my thyroid medicine over the years 3 times...it still shows I require 100 micrograms I think it’s called. I’m visually impaired so please excuse typos. I feel most of this is heart related as I’ve seen the regression of severity and the area of the body was like heart all the way down including arms legs etc when these tremors started. That’s just all I know. I’ve had my neurologist do a battery of tests too. My heart tests were the ones I had failed. But today, for the first time I feel good after 3 total stints. Almost felt I could leap tall buildings😂😂😂 but at 58 and with a knee and biceps issues I can’t really. I know how these feel. They drive you to seek answers on the internet when your doctors have no clue. My general practitioner says he thinks they’re nerve damage. Of which I do have neuropathy in my feet and hands. I’m anxious to tell him they’ve improved in severity a second time right after this last stint. I’m going to try the massage the left foot and bring circulation the best I can. Drink lots of water. That’s the only thing I recommend too. Take care.
