Dear Sir, as everybody has suggested, you need a proper x ray of the finger, in both AP and Lat views, because only that will clarify your injury pattern, mean while use ice fomentation, move only if it allows movement with minimal pain, keep limb elevated and put a crepe 2 inch bandage on the limb, Revert back with X Rays

You need to take xray of your involved hand and consult a orthopedic doctor or plastic surgeon

You have injury to your finger In this case a x ray is important to rule out fracture Please get a x ray done and revert

You need X-rays and further evaluation. Consult orthopaedic doctor
