Pain and stiffness in the middle finger joint may result from prolonged strain on the finger joints or long-term exposure to cold, damp environments, leading to severe irritation of the nerve endings and subsequent pain. Additionally, it could be due to rheumatoid arthritis, which irritates the nerve endings and thereby causes stiffness or pain in the finger joints. Upon experiencing these symptoms, prompt medical evaluation at a hospital is essential to facilitate appropriate diagnostic testing and targeted treatment.
