2. Swelling in the Joints: A Visible Sign of Inflammation
Swelling is another common symptom of RA, and it often accompanies joint pain and stiffness. The affected joints may appear visibly enlarged or feel “spongy” to the touch. This swelling is a result of inflammation in the synovial membrane, the thin layer of tissue that lines the joints. In RA, the immune system mistakenly attacks this membrane, causing it to become inflamed and swollen.
The swelling in the joints can make it difficult to perform everyday tasks, such as buttoning a shirt or opening a jar. It may also cause discomfort or pain, particularly when the joint is moved or pressure is applied.
In some cases, the swelling can extend beyond the joint itself, affecting nearby tissues and structures. For example, inflammation in the wrist joint can cause swelling in the surrounding tendons, leading to a condition called tenosynovitis. This can result in additional pain and further restrict movement.
If you notice persistent joint swelling, particularly if it is accompanied by pain or stiffness, it’s essential to consult with a healthcare provider for a proper evaluation and diagnosis. (2)
