Shoulder pain can arise from a wide range of factors due to the shoulder’s complex anatomy and frequent use in everyday activities. The joint is made up of bones, muscles, tendons, and ligaments that allow for a broad range of motion, making it one of the most flexible joints in the body. However, this mobility also makes it more vulnerable to issues such as overuse, strain, inflammation, or injury. Pain can develop gradually over time from repetitive movement or appear suddenly due to trauma. Even poor posture or sleeping positions can contribute to discomfort in the shoulder area.
The sensation of shoulder pain can vary depending on its cause. It may feel sharp, dull, throbbing, or burning, and might be constant or only occur with certain movements. Some people notice difficulty lifting their arm, rotating it, or performing routine tasks like dressing or reaching overhead. In some cases, the pain may radiate into the upper arm or neck, and it might worsen during the night or after periods of inactivity. Swelling, stiffness, or a sensation of weakness may also accompany shoulder discomfort, impacting daily function and mobility.
