Causes Of Joint Pain
There are various causes of joint pain, such as:
Injuries: Injuries to the joint, such as contusion, ligament sprains or tears, fracture, joint dislocation, soft tissue injuries, etc., that occur due to trauma and cause acute joint pain.
Infections: Infections can occur in the joint as a complication of injury or internal infection, such as septic arthritis, and osteomyelitis. This may further cause redness, swelling, warmth, tenderness, and acute pain in the affected joint. Infections may also be chronic, such as tuberculosis infection of the joints.
Degenerative changes: Degenerative changes occur due to age-related wear and tear of the joint surface, cartilage, and surrounding soft tissues. Degenerative changes of the joint, also known as osteoarthritis, are the most common cause of joint pains. Osteoarthritis most commonly affects the knees, hips, spine, and hands.
Chronic inflammation: Repetitive mild trauma to the joint and surrounding structures causes chronic inflammatory changes, such as tendinitis, bursitis, etc. Certain diseases also cause chronic inflammation in the joints which is an important cause of joint pain like gout.
Systemic Diseases: Systemic and genetic diseases associated with involvement of the bones and joints and cause joint pains are:
- Ankylosing spondylitis - a disease with a genetic predisposition that affects the spine
- Fibromyalgia - a chronic condition characterized by widespread musculoskeletal pain
- Avascular Necrosis - a condition in which blood supply to the joints is affected, leading to the death of bone tissue. This commonly affects the hip joints.
- Bone Cancer - Osteosarcoma, leukemia and other types of bone cancers that spread to bones and joints can cause severe joint pains.
- Paget’s Disease - in this disease, the bones become abnormally shaped and brittle, which can cause severe joint pains.Rickets - a deficiency of vitamin D that causes the bones to weaken and may cause joint pains.
Autoimmune disorders: Certain autoimmune diseases can involve joints and cause joint pains are:
-
Rheumatoid Arthritis - a condition characterized by chronic inflammation, stiffness, and deformity of the joints. It commonly affects the small joints of the hands in initial phase of disease.
-
Systemic Lupus Erythematosus - an autoimmune disease that causes inflammation and pain in multiple joints apart from involvement of other organ systems of the body.
Miscellaneous causes: There are many other causes of joint pains, such as viral fever, Lyme disease, sarcoidosis, juvenile idiopathic arthritis, etc.
