shoulder pain include several forms of arthritis, torn cartilage, or a torn rotator cuff. Swelling of the bursa sacs (which protect the shoulder) or tendons can also cause pain. ... Serious conditions such as a spinal cord injury or a heart attack may lead to shoulder pain.
Rotator Cuff Injury
The rotator cuff is a group of muscles and tendons that surround the shoulder joint, keeping the head of your upper arm bone firmly within the shallow socket of the shoulder. A rotator cuff injury can cause a dull ache in the shoulder, which often worsens when you try to sleep on the involved side.
Start treatment at home. In most cases, you can treat tendonitis and bursitis at home with rest, ice and over-the-counter anti-inflammatories, such as ibuprofen or naproxen. It may seem simple, but also try to avoid the motion that originally caused the pain.
Tendinopathy, also known as tendinitis or tendinosis, is a type of tendon disorder that results in pain, swelling, and impaired function. The pain is typically worse with movement.
Frozen shoulder is the result of inflammation, scarring, thickening, and shrinkage of the capsule that surrounds the normal shoulder joint. Any shoulder injury can lead to a frozen shoulder, including tendinitis, bursitis, and rotator cuff injury(rotator cuff syndrome).
One of the most common problems after shoulder surgery is stiffness of the shoulder joint. For some surgical procedures, a period of time of immobilization is necessary to allow for adequate healing.
