Pain, swelling, soreness, and heat in the joints, as well as morning stiffness that lasts more than an hour, are all symptoms of inflammatory arthritis. Psoriatic arthritis, gout, rheumatoid arthritis, systemic lupus erythematosus are the most frequent types.
The immune system malfunctions in several disorders, causing inflammatory substances to be released. As a result of the inflammation, joint swelling, increased joint fluid, cartilage and bone deterioration, and muscle loss might occur. Joint nerves are also triggered, resulting in discomfort. Other nerves in the body may be directly activated by the inflammatory substances, resulting in pain.
Inflammatory pain can be induced by a variety of factors, including:
- Bone erosion: The loss of bone due to disease processes is known as bone erosion. Rheumatoid arthritis is an example of erosive arthritis, which is defined as joint inflammation (arthritis) with bone damage. Bone erosion, as opposed to osteoporosis, is the loss of bone in a specific area.
- Muscle weakness: Joints are put under higher stress when muscle strength is reduced.
- Centralized pain: Inflammatory arthritis can make you more sensitive to pain because of the chronic (long-lasting) discomfort.
- Swollen joint capsule. Fluid from the inflamed synovium builds up in the joints, causing pain and stiffness.
- Synovitis. Inflammation of the synovial membrane is referred to as synovitis. Synovial joints, which have cavities, are lined by this membrane. It is common for the condition to be painful, especially when the joint is moved. Synovial fluid accumulation causes the joint to swell.
- Joint fusion. Joint fusion, also known as arthrodesis, is a surgical procedure used to relieve severe arthritic pain. It entails fusing the bones in your painful joint together to form a single solid bone. The fused bone is usually more stable, resulting in less pain.
- Ligament damage. A sports injury is a common cause of ligament damage. Knee movement is substantially restricted due to a damaged ligament. As a result, the leg is unable to rotate, turn, or twist. If various medical treatments fail to heal a torn ligament, surgery may be required.
