When a tendon is inflamed, it can cause swelling, pain, and discomfort. Another problem called tenosynovitis is linked to tendonitis. This is the inflammation of the lining of the tendon sheath around a tendon. Usually the vagina is inflamed by itself, but both the vagina and tendon can be inflamed at the same time.
