Thank you for the query.
Yes, it could be the fracture
. You never know, that is why after trauma which gives risk of fracture, X-ray should be performed. Fractures
usually get healed in 4 weeks if injured area is immobilized. Otherwise, it can heal much longer. Moreover, in some cases not healed property fracture can give lack of function of the wrist. That is why you should consult your doctor and have an X-ray performed anyways.
Hope this will help.
