Are you doing "hand work" now? Is this worse after working on your jewelry projects?

Is it worse after fasting all night and before you eat?

Numbness and tingling may improve with night splints on your
wrists. These carpal tunnel braces, keep you from flexing your wrists while sleeping and keep the area where all the nerves and blood vessels go into the hand...open.

There are some comfortable ones now...made by Futuro...and very affordable on Amazon. CVS carries them at double the price:

This one is very comfortable and helps me quite a bit. My hands have had this problem since I was pregnant over 30 yrs ago.
Mine is due to a hypothyroid issue. I don't wear mine every night but I do get flares and then I wear the brace for at least a month and it seems to control things for me. I had EMGs in my arms back when it was severe during pregnancy, but I have avoided the suggested surgery so far.

I'd try one of these soft braces --say the right one for your dominant hand, and see if it works for you. Then if so, you can buy the left later.

Also as we age, your metabolism changes and blood sugars can go down in the night and tingling/numbness in the hands can be common. This trigger tends to vary during the day, and come and go. If you suspect this factor, you can have a small snack (avoid sugar consumption), before bed and see if your hands are better the next morning. I use a protein energy bar called Zone perfect for this, as they have protein added to them, and keep blood sugars stable longer. Even a 1/2 bar works for me in the night. Some nights I don't have one, but if I have a small dinner or no dinner, I always have a protein bar in the night. Target, WalMart and Kroger's sell these useful protein bars.
