Hi welcome to Health care magic forum. You are thinking that the injury
is a sprain
, but it appears to be fracture
of metacarpals or phalynges, that is why the pain is so prominent and continuous.
I advise you to consult an orthopedic surgeon for diagnosis and tratment. you may need to have an xrar of the hand A.P, and lateral view to have an exact position of the fracture if it is there,if fracture is there you need to have plaster cast for 6 weeks for it io be healed. if only majr sprain some times you may need a cast for a short period.
I hope this information is use full to you . Wishing for a quick recovery and thanks for calling.
