This is rather difficult. We can't diagnose on the internet.
You really need testing for B12 and Vit D to see where you are at for those 2 critical things.
The only thing I can go on now, is the fact that you drink. Drinking alcohol depletes magnesium from the body. Magnesium is the muscle relaxing mineral, whereas calcium is the contraction one.
You can try soaking the hand and arm in epsom salts daily.
3 tablespoonfuls to a small tub of warm water. Or take a bath in it. 3-4 ounces in a bathtub with warm water.
If this works then go to oral tablets. Your goal orally is 1/2 the RDA.
This thread has information on how to select the best oral form (do not get magnesium OXIDE).

Anything further, like arthritis, neck issues or Thoracic outlet syndrome, should be evaluated by a doctor.
