2. Rheumatism: a kind of joint inflammation caused by hemolytic streptococcal infection, cumulative rheumatism of the finger joints, which can cause finger swelling and pain, and in severe cases, finger deformation can also occur.
3. Fracture: Finger fracture caused by external force on the finger can also cause pain in the finger joints and inability to move the finger.
4. Purulent dactylitis: bacterial infection of the hand caused by tiny abrasions or puncture wounds, the most important causative organism is Staphylococcus aureus. Needle-like pain can occur, then develop into severe throbbing and swelling of the finger, if necessary, need to be incised and drained.
