I said this on 20th June, was I completely wrong?

Exersise your hand don't rest it. Arm out stretched, push your fingers back slowly and feel the stretch, then push your fingers down, thumb as close as you can get it to your wrist, slowly and again feel the stretch. Then with a limp wrist waggle / dangle your hand and gently shake it. It'll be gone in two weeks if you do this at least 3 times a day.

Do not have surgery and don't take drugs.
