Hi welcome to Health care magic forum. It appears that there is an abrasion and brusing of tissues after some time. The brusing is restricting your movements of the limb.
There is chance of secondary infection of the swollen tissues. So i advise you to consult an orthopedic surgeon for diagnosis and treatment. You may need to have an x ray
for excluding the possibility of any minor fracture
Besides i advise you to follow immobilization to make the injury
to heal faster.
I wish you fast recovery and thanks for calling.
