I hurt my wrist by lifting heavy thing now my wrist hurts on the pinky side pain radiates to my finger but I can still move my wrist.

Many possibilities. Ulnar sided wrist pain can be attributed to a lot of pathologies. The most common would be ecu tendonitis or a tear/sprain of the tfcc. I would recommend a through exam by a hand surgeon and possibly an mri. Wear a volar (palm side) wrist splint, avoid heavy lifting and take ndaids for temporary relief.
You either . Irritated the tfcc cartilage in the wrist joint or possibly the ecu tendon on the outside of your wrist. Try ice, nsaids, and a brace for a few days should get better.
