Orbicularis oris muscle. In human anatomy, the orbicularis oris muscle is a complex of muscles in the lips that encircles the mouth. Until recently, it was misinterpreted as a sphincter, or circular muscle, but it is actually composed of four independent quadrants that interlace and give only an appearance of circularity.
Many people feel an itching, burning or tingling sensation around their lips for a day or so before a small, hard, painful spot appears and blisters erupt. Blisters. Small fluid-filled blisters typically break out along the border where the outside edge of the lips meets the skin of the face.
