re: Pain in elbow where forearm meets at the top and numb hands and arms when I wake up.

Do you work out? I had the same issue. In my case I had cubital and carpal tunnel syndrome. I had to have surgery on both my wrist and my elbow to fix it. Now I’ve got scheduled surgery to fix my left arm. I got it from working out. In the elbow it’s likely a trapped ulnar nerve.

Symptoms were if I layer wrong my arms would go completely numb. Brushing teeth, etc. would make them go numb as well.

Set up an appointment with a neurologist and they can test the magnitude of your issues. Good luck.
