I used to have some minor wrist pain on my right wrist for years, after starting to train for tuck planches, it somehow healed itself through the wrist warmup exercise.
Right now, my left wrist is suffering from a more serious pain.
It started about more than 1 week ago. I don't know if it's because I just started training my false grip then, or is it just too much practicing of tuck planches?
I do tuck planches 5 days a week on weekdays.
The exact location of my pain is at my left thumb. Every movement that involves it will give me pain. Gripping something on the left hand feels weak and slight pain.
Here's a picture of where my pain is. What should I do?

Wait till the pain goes away?
Stop training for a while? Get an X-Ray? Massage it?
