About the Symptom

Knee pain can be throughout the joint, in the front, back, either or both sides. The pain may be pressing, sharp or dull in nature.

When to see a doctor

Seek professional care if you experience any of the following symptoms

  • Violaceous / purpuric rash

  • Easy bruising

  • Vomiting of blood

  • Melena (black stools)

  • Recent weight loss

  • Numbness / sensory disorder

Possible Causes

Generally, Knee pain can be related to:

  • Osteoarthritis (OA)

    Wear and tear of the joint cartilage over time. Risk factors include repetitive joint movements and carrying heavy loads for many years.

  • Rheumatoid Arthritis (RA)

    A chronic inflammatory disease where the body's immune system attacks multiple joints, most commonly in the hands and feet. The cause and trigger is unknown.

  • Osteonecrosis

    A condition where bone loses its blood supply and dies. It can be caused by direct injury to the bone (e.g., a fracture or dislocation) or indirect injury (e.g., alcohol, smoking, diseases, medications, or radiotherapy).

  • Lumbar Vertebrae Disk Herniation
  • Lumbar Spondylosis
  • Adult Still's Disease
  • Hypophosphatasia (HPP)

  • Common Cold (Upper Respiratory Tract Infection)
  • Congenital Hemophilia

Related serious diseases

Sometimes, Knee pain may be related to these serious diseases:

  • Decompression Sickness

    Decompression sickness (also called "the bends") refers to problems caused by a rapid decrease in surrounding pressure (either air or water). This causes gases to dangerously shift out of the bloodstream. It most commonly occurs during scuba diving when surfacing too quickly. Rarely, it can happen in airplanes, typically in military pilots traveling at high speeds through upper and lower atmosphere layers.
