One of the main causes of disability suffered by patients is joint pain. Musculoskeletal pain, particularly related to the neck and back joints, affects millions of people and is the most common form of chronic pain. Most joint pain is due to some form of arthritis, which includes more than 150 different forms and affects more than half of the population over 50. Other causes of joint pain can include fibromyalgia, chronic back pain, spondyloarthritis and psoriatic arthritis, systemic diseases, and crystal deposit disease (chondrocalcinosis or pseudogout). Other conditions such as bursitis, gout, strains and sprains can also play a role in joint pain which can be felt in any part of the body including the feet, ankles, hands, shoulders, hips, knees, shoulders, back and wrists. Patients suffering from joint pain may experience reduced mobility in the affected area and find that their quality of life or ability to perform simple tasks is greatly reduced due to a lack of effective treatment to reduce the pain.
Swollen joints occur when there is fluid in the tissues around the joints. It can be very uncomfortable and can make it difficult for the affected joints to move. In some cases, the swelling can cause the affected joints to enlarge or appear oddly shaped. Joint pain and swelling can affect more than one joint at a time. The most common joints affected by pain and swelling are the elbows, wrists, shoulders, base of the spine, knuckles, hips, knees or ankles. There are two types of joint pain and swelling: acute and chronic. Acute joint pain and swelling come on quickly and last for a short time, for example in the event of an injury. Chronic joint pain and swelling come on slowly and cause long-term problems. This is likely caused by an underlying condition, such as a type of arthritis.
