How can you quickly heal bruises on knuckles?

SImple means: With injury to our tissues, inflammation (red, hot, swelling, tenderness) occurs. There is leakage of blood from damaged capillaries and veins which collects under the skin and causes the purple blue coloring we call a bruise. Over time, damaged tissues heal and blood collections are reabsorbed. Protect the area to promote fastest healing. Motrin/advil will help.
