If you were a diabetic, the tingling sensation could be significant. If you are not diabetic, then it is probably a sign of hyperawareness of body sensations. Same with 'vibrations.' Your vibrations could be slight muscle twitching related to nervousness or even hyperawareness of blood circulating through your body.
Your tachycardic episodes are brief and not dangerously high, and they correlate well with either daytime or nighttime panic attacks, which have different manifestations. You can google that.
Your red hands are probably showing the normal effect of gravity, especially if you are fair-skinned and the day is warm or you yourself are slightly overheated.
Your doctor is right: Your tests show that your heart is healthy, that you are healthy overall, and you'd be a lot happier if you could control your over-sensitivity to bodily 'noise' that has no health significance.
Of course, after people get used to 'listening' nervously to what's going on in their bodies, they generally cannot just shut off that awareness, and that is where professional help comes in.
Are you seeing someone for your health anxiety issues? If not, I do suggest that, because you can get help that will allow you to live a more normal life, giving attention to things that are far more valuable and rewarding than listening to the inside of your quite functional body.
thank you. I'm going to have a nerve test and sleep test done. I'm sleeping almost all night with regular vibration in the morning. A little less tingling and pains in the hands but I get slight vibrations in my left arm & hand during the day. I still have strength. So my symptoms change every few days. In the past few days I've been startled by a couple of things...both times an electric shock went straight down to my feet.
