No one can diagnose you from here but your doc or a physiotherapist or massage person can.
Ugh, sorry you have had pain for this long! Perhaps when your wrists were pulled up violently like that, you sprained your wrists and stretched the ligaments. An unresolved sprain can absolutely cause chronic wrist pain. Carpel tunnel syndrome can also cause this pain. Does ibuprofen relieve it at all? So, I'd see your primary care doctor or an orthopedist to get an xray and evaluate the situation. Let us know what they say!
