What is bursitis?
It is a painful condition that affects many joints of the body.
Bursae are fluid filled sacs (cavities) found near the joints. They act as a cushion and contains a fluid which acts as a lubricant that reduces friction between. Together they help in easy movement of joints.
Sometimes because of some causes this bursa gets irritated and gets swollen (filled with extra fluid) putting pressure on nearby joint, the resultant condition is called bursitis.
Amongst the various joints of the body any one can get affected. Joints near which bursitis can be commonly found are- shoulder, elbow (tennis elbow, golfer’s elbow, student’s elbow), ankle, knee (clergyman knee, housemaid knee) and hips.
Common risk factors are:
Obesity: heavy weight puts much pressure on joints and surrounding areas.
Manual workers: repetitive strenuous physical exertion is one of the most important factors causing bursitis.
Athletes: those who are regularly engaged in some sort of physical exercises are also prone to get bursitis.
Causes and symptoms
Some of the main causes of bursitis are injury, overuse and infection.
Overuse: bursitis can also occur if the nearby structures has been overused (commonly by repetitive movements).
Injury: in cases of injury, tissues inside the bursa gets irritated causing pain and tenderness. It may occur by hard blow to affected area.
Infection: it can occur in bursae near skin by a cut as it gives access to bacterias to enter the bursa.
Other health condition: some underlying conditions (such as gout, rheumatoid arthritis or scleroderma) can cause crystal formations inside the bursa which ultimately causes bursitis.
Pain: which increases with joint movement, pressure and sometimes at night.
Tenderness of affected area
Swelling in surrounding area
Restriction of joint movement and ultimately complete loss of joint movement.
Area hot to touch: when underlying infection is present. It may also cause fever.
Untreated bursitis can lead to progressive or persistent pain with complete loss of movement of joint.
Diagnosis and treatment
A thorough joint examination along with history of recent activities help in getting the clear picture of this condition.
Some investigations that can be useful to rule out other similar condition and make a diagnosis are:
