Hip bursitis can be a very painful condition and can dramatically limit activity. It occurs when a bursa -- a fluid-filled sac that reduces friction between a bone and a muscle -- becomes inflamed. There are multiple bursae in the hip; however, the one most commonly affected is the greater trochanteric bursa.

Edema is swelling caused by excess fluid trapped in your body's tissues. Although it affects all parts of the body, one of the first indications of edema is typically the presence of swollen feet. While a low protein intake may be one of the many causes of edema, consult a doctor to determine the cause in your case.

Many women suffer from swollen ankles during pregnancy, but it also is possible to suffer from swollen ankles after you give birth. Swelling is sometimes referred to as edema and is caused by fluid and blood retention.

When hands ache at night time because of arthritis pain, it is difficult to get a good night’s sleep. Instead of floating off to a dream state, feelings of agitation, annoyance and a desire for relief and a quick remedy are all too consuming.

A tendon is a thick, fibrous cord that connects muscles to bone in your body. Tendonitis is the painful inflammation of a tendon secondary to injury. The most commonly affected tendons are located in the shoulders, elbows, wrists and heels. Untreated tendonitis can progress to a tendon rupture.

Trigger thumb, also called stenosing tenosynovitis, is caused by a problem with the flexor tendon, which bends the thumb, and the tunnel it moves through. The tunnel is made up of a series of rings, or pulleys, that keep the tendon close to the bone.

Ulcers are open sores in the lining of the gastrointestinal tract. They develop mostly in the stomach, esophagus or duodenum. Ulcers form when the environments of these surfaces are so acidic that their mucosal linings slowly erode.

Patellar tendonitis -- also spelled tendinitis -- is the inflammation of the tendon that connects the patella, or kneecap, to the top of the tibia, or shinbone.

The shoulder joint is a shallow ball-and-socket joint between the humerus -- upper-arm bone -- and the glenoid fossa of the scapula -- shoulder blade. A unique joint, the shoulder has only one bony attachment to the rest of the skeleton in the clavicle -- collarbone -- where it attaches to the scapula.

The rotator cuff is a series of four small muscles that allow the shoulder to move. If these muscles get torn or damaged, it can impact your ability to move your shoulder. While surgery is an option, there are non-surgical ways for the shoulder to heal when the muscles are not torn completely.

Professional basketball players compete in 82 games during the regular season and their knees take a tremendous amount of abuse over the course of the year. When a player's patellar tendon swells from jumping or falling, it causes a condition referred to as jumper's knee or patellar tendinitis.

Author Andrew Biel notes in "The Trail Guides to the Body", that a pivot joint allows one bone to rotate around another. The first and second cervical vertebrae pivot to allow neck movement from side to side, and the ulna and radius in the forearm pivot from side to side, as well.
