Two weeks ago i had a cycling accident to which i fell off and knocked my on hand hard on the ground. my wrist occasionally feels painful whenever i pick up something, put pressure on my wrist or try move my wrist perpendicular. is this a sprain?

Wrist pain : A wrist fracture can be subtle and often missed on an X-ray right after a fall on the wrist. In the general, a wrist sprain can take up to 6 months to improve. See a doctor in person

Possible fracture : Small hairline fractures may be missed early but can be better visualized on later films. An orthopedic hand specialist is a good resource
