Hi Sander
Maybe you should avoid the table pose for a while. If you want to gently open up your hand or hands again then I would avoid a pose that puts ALL your body weight on your wrists. Table pose puts more weight through the wrists than the fingers so I just get an idea it is more related to something (perhaps nerve related) through your wrist.
Have you tried one hand at a time pressing gently through the palm and wrist while sitting on the floor?
If that’s not the issue then I would really want to ask more questions.
Have you seen a doctor/specialist at all? If so, what did they say?
See you back here
Namaste
Gabrielle 🙂
