Several years ago, if you'd told me I'd be publicly talking about this, I would have thought you were nuts.
As a long term diabetic, I have noticed the gradual changes that have happened to me (well, and the not so gradual ones). I won't belabor the usual things here. But one odd one has recently appeared.
When giving myself an injection (predominantly on the left abdomen), I have noticed all sorts of strange sensations. Sometimes it has been a tingling in other parts of my body (arms, legs), sometimes it is a sharp pain in my back. One time I was unable to move my left arm (hand was fine).
It's a bizarre sort of acupuncture; it does seem to only happen with the longer needles. I am not sure why this has only recently started, and the pain is never bad enough to stop. I am not too concerned about it, but it is something that is different that I have found very little mention of.
