Welcome, Oregon Mom! I'm glad you found us. I, too, am diabetic (Type 2) but what you described sounds like fibro to me. I have tingling in my hands sometimes but it goes away. I'm not positive but the numbness from diabetes doesn't go away (neuropathy). I think that when the muscles tighten up it pinches nerves and causes the tingling. Soon and I get moving, the tingling leaves. Also, I get tingling in my hands if my blood sugar is too low.
Be sure to read the Fibro 101 thread...the second thread on the forum. There are links to a lot of good info about fibromyalgia. Also, read back posts. There is a lot of information in them too. Don't hesitate to ask questions. That's what we are here for.
I'm so glad you joined us and I hope to hear more from you soon.
