Natural process: When there is injury to our skin, inflammation occurs which means the area becomes red, warm, tender and with swelling. The swelling occurs under the skin layers and then can leak out of an open wound. The fluid contains water, protein, electrolytes and cells that give it color. This is a natural process and aids in healing. As it heals, the drainage will decrease. Keep it covered.
