Crepitus is frequently caused by arthritis or a prior joint injury. A cracking or popping sound and an unusual sensation in your joint, on the other hand, might be produced by air in the tissues, which could be caused by a wound or some types of bacterial infections. Crepitus should not be used as a sole indicator for ruling out serious disease. Joint pain with swelling, fever, and inability to sleep are all signs of arthritic disease. The two most common forms of arthritis are osteoarthritis and rheumatoid arthritis. Osteoarthritis occurs when the cushioning cartilage between bones at one or more joints wears away. This allows bone surfaces to rub together, causing pain and stiffness. It is the most common form of arthritis and affects millions of people. Rheumatoid arthritis is a chronic condition that causes inflammation of the joints. It can affect any joint but most often starts in the hands, wrists, feet, legs, and neck and may cause major disability if left untreated. The symptoms of arthritis can be managed with medication and/or physical therapy. If you have severe arthritis, you might need assistance with daily activities such as getting up from a sitting position or walking. In this case, either a caregiver or assisted living facility can provide the necessary care.
