what causes stiff sharp pain in shoulder
Bursitis: A bursa is a sac over the joints to provide a cushion to the joints and muscles. These bursae can become swollen, stiff, and painful after injuries. Heart attacks: Although the problem is the heart, heart attacks can cause shoulder or neck pain, known as referred pain. Broken shoulder blade: An injury to the shoulder blade usually is associated with relatively forceful trauma.
Neck problems and injuries most commonly occur during sports or recreational activities, work-related tasks, or projects around the home. Neck pain may feel like a kink, stiffness, or severe pain. Pain may spread to the shoulders, upper back, or arms, or it may cause a headache. Neck movement may be limited, usually more to one side than the other. Neck pain refers to pain anywhere from the area at the base of the skull into the shoulders.
