Thank you. Both of those answers are exactly what I need to be considering, thank you for that.
I will wait until it happens again and then try to get a picture. In the mean time I will research more on those. Thank you.
Hello, it may be a carpal tunnel issue, I would see your GP, he will be able to tell you for sure what is going on. In the meantime, wearing a hand brace may help some.
That sounds uncomfortable! Have you been doing any work with that hand lately? Gardening, working a tool of some sort? Anything that would be different than your norm? It may be a hand cramp. Which can come about from dehydration as well as overuse, magnesium deficiency, poor circulation. There is also something associated with diabetes that can cause a hand to cramp. https://www.healthline.com/health/hand-cramps#causes Tell us more in case I'm getting the symptom wrong.
