Bursitis is the inflammation of a bursa. A bursa is a small, fluid-filled sac that acts as a cushion between bones and tissues such as skin, tendons, and muscles. Bursitis often occurs in the shoulder, elbow, hip, or knee.
Symptoms of bursitis include pain and tenderness at the affected joint, swelling, redness, and warmth. The pain may worsen with movement or pressure on the joint. Bursitis is usually caused by overuse or repetitive motions. It can also be caused by an injury or infection.
Treatment for bursitis typically includes rest, ice, and heat therapy. Over-the-counter pain relievers may also be used to help relieve pain and swelling.
1Early Symptoms of Bursitis

Bursitis occurs when the bursa, a small fluid-filled sac that acts as a cushion between bones and tendons or muscles, becomes inflamed. This can happen due to overuse, injury, or infection. Bursitis often affects the shoulder, elbow, hip, and knee.
Symptoms of bursitis include pain, tenderness, stiffness, and swelling in the affected area. The pain may get worse with movement or pressure on the area. Bursitis is usually treated with rest, ice, and over-the-counter anti-inflammatory medications. In some cases, physical therapy or corticosteroid injections may be necessary.
Pain
Pain is the most common symptom of bursitis. The pain may be sharp or dull and it may come on suddenly or gradually. The pain may be worse when you move the affected joint or press on it. You may also have stiffness and swelling in the joint.
