Rigidity:
Shoulder stiffness can be caused by issues with the surrounding muscles, tendons, ligaments, or cartilage. Each of these structures is susceptible to inflammation. You may experience pain in your shoulder joints when you move them, or you may find it difficult or painful to move your shoulders without experiencing significant pain. Shoulder stiffness can make it difficult to lift heavy objects or perform other arm-related actions, such as reaching aloft to pick up an object.
Patients with rheumatoid arthritis typically report feeling rigid and achy upon awakening. So, presume you experience symptoms of stiffness that worsen when the articulation is inactive. In this case, this is a sign of rheumatoid arthritis, and you should seek a diagnosis from your doctor.
