Right shoulder pain can develop from many of the same causes that affect the left shoulder, including muscle strain, tendonitis, rotator cuff injury, arthritis, posture problems, and repetitive movement. The discomfort may be mild and temporary, or it may become persistent enough to affect sleep, work, exercise, and daily movement.
Common symptoms include aching, stiffness, tenderness, weakness, limited range of motion, or pain that worsens when lifting, reaching, or rotating the arm. Pain may also be felt near the shoulder blade, upper back, neck, or down the arm depending on the tissues involved.
In some cases, pain felt around the right shoulder or shoulder blade may be referred from another area of the body. Gallbladder problems, abdominal conditions, or irritation near the diaphragm can sometimes create discomfort that is perceived in the right shoulder region. Pain with fever, nausea, severe abdominal pain, chest symptoms, or sudden worsening should be evaluated promptly.
Treatment depends on the underlying cause. Conservative care may include rest, stretching, posture correction, physical therapy, and avoiding activities that aggravate symptoms. If pain persists, becomes severe, or follows an injury, medical evaluation can help determine whether imaging or additional treatment is needed.
Because right shoulder pain can come from muscles, joints, nerves, or referred sources, identifying the pattern of symptoms is important. Timely assessment can help improve comfort, restore function, and reduce the chance of recurring pain.
