In severe tendonitis, the hand is in a state of chronic pain, or the fingers are in a state of chronic flexion and extension, and even lifting heavy objects and carrying a little something is not possible. Female patients, especially those who are menopausal or breastfeeding, and those who are often engaged in domestic work, should keep their hands warm, wash their hands with warm water, and move their fingers and wrists frequently. After a long period of time engaged in a certain household activity, or holding a child, cooking, knitting a sweater, try to rest, or massage yourself locally or apply heat to help prevent tendonitis, or to prevent recurrence.
