I Wake Up In The Middle Of The Night And

I wake up in the middle of the night and one or both hands are "asleep". Then I adjust and go back to sleep in a different position to alleviate the problem, only to have it happen to the other hand. It happens in streaks. Sometimes several nights in a row. Then nothing for nights in a row. Then back again.
Trying to figure out what is causing this issue. Female between 44-50 years of age. Not menopausal. Non smoker, rare drinks of alcohol. Not on any medications for any conditions.
