Your shoulder is a delicate joint area made up of ligaments, tendons, cartilage, and connecting bones. Shoulder pain often results from injuries such as rotator cuff tears, as well as less serious strains caused by heavy lifting or sports-related incidents. Some other causes of shoulder pain are Bursitis, Tendinitis, Osteoarthritis, and degenerative arthritis with bone spurs. Swelling, tenderness, redness, pain, and warmth are all common symptoms of shoulder pain. Immobility of the shoulder and even the whole arm can be an enormous hindrance, especially when the shoulder on the dominant arm is in pain. Smokers and those who put repetitive stress on their shoulders are at an increased risk of shoulder injury and damage.
