Wrapping a sprained thumb does not only help stabilize the injured thumb, but also compresses it. Compression aids in stimulating the flow of lymph fluid, which carries important nutrients to the damaged tissues surrounding the injury. Lymph fluid also removes waste from cells and body tissues which is an important function during the tissue regeneration process. Wrapping the thumb also speeds the recovery process and keeps the injury from getting worse. In order to be completely effective, the bandage must be removed, the injury left to rest, and the bandage re-applied a few times a day. In this way, the lymphatic system can complete its evacuation of the injury site.
