Assessment of pain according to localization

Rheumatoid arthritis (rheumatism) mainly affects the finger base and middle joints. If the metacarpophalangeal joint (MCP) on one side is affected, the middle finger of the other hand is also usually affected symmetrically. The arbitrary infestation of the metacarpophalangeal joint or any other finger joint indicates gout.

If there is pain in the middle finger joint (PIP), it can be rheumatism. The joint of the other hand is then usually also affected. In rare cases, the so-called finger polyarthrosis (Heberden’s arthrosis) can be the cause of pain in the middle finger joint of the middle finger and in all other fingers.

Pain in the middle finger joint (DIP) is mainly caused by psoriatic arthritis or Heberden’s arthritis. In psoriatic arthritis, either almost exclusively the end joints of the fingers are affected or the entire joints of the middle finger. If the metacarpophalangeal, middle and end finger joints are affected, this is also known as radiation.

The fingertip is one of the most sensitive areas of the human body. It is home to numerous nerve endings that ensure a particularly well developed sense of touch. If the fingertip hurts, injuries to the bones, tendons and joints are rarely the cause.

Often there are superficial injuries of the skin or sensations of the nerves, caused by various diseases. If there are no minor injuries to the skin, the pain is often caused by harmless sensations caused by extreme cold or heat, unusual positions of the arm or heavy strain on the hands.Only rarely are serious circulatory disorders or nervous diseases underlying. Diabetic polyneuropathy, for example, can be a disease of the nervous system that can begin with disorders of the sensitive nerves at the fingertip.

Pain in the middle finger caused by an injury to the joint capsule is usually caused by a strain and a rupture of the capsule. If the joint on the middle finger is severely overextended, a rupture of the joint capsule with dislocation of the finger can also occur. Inflammation of the joint capsule becomes apparent through pain, swelling, redness and overheating. This can be caused by overexertion of the joint.
