No problem, yes connective tissue diseases affect the tendons, ligaments etc. I found this;
"Many autoimmune disorders affect connective tissue in a variety of organs. Connective tissue is the structural tissue that gives strength to joints, tendons, ligaments, and blood vessels.
In autoimmune disorders, inflammation and the immune response may result in connective tissue damage, not only in and around joints but also in other tissues, including vital organs, such as the kidneys and organs in the gastrointestinal tract. The sac that surrounds the heart (pericardium), the membrane that covers the lungs (pleura), and even the brain can be affected. The type and severity of symptoms depend on which organs are affected."
I hope that helps!
