hi there, initially after your finger was hurt you could move it but later as a reaction to injury and bruising there is edema and swelling which is causing the restriction of movement. It would be wise to get an x-ray and rule out fracture
. In the mean while you can put a splint
, do not move it , keep it in an elevated position and take some anti-inflammatory like brufen
till you get a consultation.The sooner it is done the better as if there is a fracture it will unite improperly leaving your finger with deformity
. Take care.
