1 At the ends of each of our chromosomes are sections of DNA called telomeres. 2  Telomeres protect the ends of the chromosomes during DNA replication by forming a cap, much like the plastic tip on a shoelace.
Osteoarthritis (OA) is the most common type of finger arthritis. OA is also called degenerative joint disease because it is caused by wear and tear on your joints as you age. In OA, the protective tissues in your joints deteriorate with time allowing bare bone to rub on bone. This cause joint pain and swelling.
Finger pain can be caused by disease or injury affecting any of the structures in the finger, including the bones, muscles, joints, tendons, blood vessels, or connective tissues. Joint pain is a feature of joint inflammation (arthritis) that may occur in the joints of the finger bones. This can sometimes be accompanied by redness, swelling, or warmth of the joints. Both osteoarthritis and rheumatoid arthritis (RA) commonly affect joints of the fingers. Trauma or injury to the finger, such as bruises, dislocations, and fractures of bone are all common causes of finger pain. Tumors of the structures in the finger are a very rare cause of finger pain. Certain conditions such as diabetes can cause damage to the nerves, resulting in pain, numbness, or tingling of the arms and legs.
