Flesh pain in the nail, consider the presence of gingivitis. Inguguinitis is a purulent bacterial infection of the skin and surrounding tissues in the nail grooves that form along the sides of the nails, often caused by tiny puncture wounds, barbs, and cutting the nails too deeply. The causative organism is mostly Staphylococcus aureus. Nail groove inflammation often occurs on one side of the nail groove subcutaneous, first for the local redness, swelling, heat, pain. When pus develops, white pus spots appear under the skin of the nail groove, and there is a sense of fluctuation, but it is not easy to break. Inflammation may spread to the nail root and extend to the other side of the nail groove, forming a semicircular abscess, spreading to the nail to form a subnail abscess. The latter may spread deeper as a result of the infection, forming phalangeal and chronic onychomycosis.
