I hit a volleyball this after with the underside if my hand (made a fist) it bent my wrist backward causing pain. Now about 7 hrs later it is still very painful to my hand backwards and all to put pressure on my wrist. These are fairly sharp pains. It does not hurt to pick things up or grip most objects. There is only pain when I move my hand. Thank you.
Dear patient You must have injured wrist ligament due to extreme stretching while playing and this is leading to pain. Still possibility of fracture needs to be ruled out, and I would advise X-ray of involved wrist with hand anteroposterior and lateral views.  Visit radiology center nearby you and get it done. If report is normal diagnosis is wrist sprain.  Avoid game for 2 weeks and apply wrist binder for 3 weeks. Start tab diclofenac plus serratiopeptodase combination twice a day for 5 days for pain relief. If X-ray report is abnormal you need to consult expert orthopedic surgeon with report.  All the best.
