Muscle And Tendon Pain
Muscle and tendon pain may develop in a psoriatic arthritis patient. When the immune system of an affected individual attacks and damages tissues lining their joints, they begin to swell and become inflamed. The swelling and inflammation can cause the muscles that neighbor the joint to become overstretched. An overstretched muscle can cause an individual to experience pain, as some of the small muscle fibers have been torn.
A tendon is a structure in the body made of strong fibrous collagen fibers that attach an individual's muscles to their bones. Swelling in the joints precipitated by psoriatic arthritis can cause the tendons to become stressed and overworked from holding the muscle to a bone in an area where swelling and inflammation are present. Muscle and tendon pain are common when swelling in the joints becomes severe due to psoriatic arthritis.
