Shoulder stiffness can be a problem with the muscles, tendons, ligaments, or cartilage around your shoulders. All of these structures can be affected by inflammation. You can feel pain in your shoulder joints as you move them or feel the shoulders locked or difficult to move without significant pain. Shoulder stiffness can make it difficult to lift heavy items or perform other actions involving your arms, such as reaching overhead when you try to pick something up.
The stiffness usually gets worse when you sleep, especially in rheumatoid arthritis, where patients typically report waking up feeling stiff and sore. So, suppose you’re experiencing stiffness symptoms that worsen when you leave the articulation inactive. In that case, this is a sign of rheumatoid arthritis, and it is a good idea to visit your doctor for a diagnosis.
