Understanding Crepitus: Causes, Symptoms, and Treatment Options

Crepitus is a sensation of cracking or crunching under the skin, often accompanied by pain. It can occur in various parts of the body, including the joints, muscles, and tendons. The sensation of crepitus is usually caused by inflammation, injury, or degenerative conditions that affect the tissues beneath the skin.

Some common causes of crepitus include:

1. Arthritis: Inflammation of the joints can cause crepitus, which may be accompanied by pain, stiffness, and limited mobility.
2. Tendinitis: Inflammation of the tendons, which connect muscles to bones, can also cause crepitus.
3. Bursitis: Inflammation of the bursae, small fluid-filled sacs that cushion joints and reduce friction, can lead to crepitus.
4. Muscle strains or tears: Injury to the muscles can cause crepitus, especially if there is inflammation or bleeding within the affected area.
5. Fractures: A broken bone can cause crepitus, especially if the fracture is displaced or has not healed properly.
6. Soft tissue infections: Infections of the skin and underlying tissues can cause crepitus, which may be accompanied by redness, swelling, and warmth.
7. Degenerative conditions: Conditions such as osteoarthritis, rheumatoid arthritis, and tendinopathy can cause crepitus over time due to the wear and tear on the joints and surrounding tissues.

If you are experiencing crepitus, it is important to seek medical attention to determine the underlying cause and receive proper treatment. Your healthcare provider may perform a physical examination, take a medical history, and order diagnostic tests such as X-rays or an MRI to help diagnose the cause of your symptoms. Treatment will depend on the underlying condition, but may include medication, physical therapy, or surgery.
