Causes

The pain is caused due to the damage in the joint. Joints are basically made of 3 parts. They are:

  • Cartilage – This is a hard, polished coating to the joint ends. This helps the bones to slide smoothly upon each other.
  • Capsule – This is a tough membrane that encloses the parts of the joints.
  • Synovium – This is a thin membrane that lines the capsule and deposits synovial fluid that helps in lubricating the joint and nourishing the cartilage.

 

The common causes of joint inflammation include –

  • Autoimmune disease
  • Wear and tear of joints
  • Broken bone
  • Bacterial or viral infection
  • Metabolic abnormalities

 

There are 2 major categories of arthritis –

  • The first category caused by wear and tear of cartilage, i.e. ostearthritis
  • The second category caused by inflammation of the synovium, i.e. rheumatoid arthritis
