what causes sore knuckle joints
Knuckle pain may develop as a result of conditions affecting any of the structures in the knuckle, including skin, nerves, muscles, joints, tendons, bones, ligaments, blood vessels, and connective tissue. Injury from trauma and osteoarthritis are common causes of knuckle pain.n many cases, several knuckles may be affected. Inflammation within the knuckle causes swelling and pain.
