A paronychia usually forms where there is an ingrown area of nail. An ingrown nail is a margin of nail that pokes into the skin, near the top of the nail. Ingrown nails are caused by trimming the corner of a nail too short .

Conventional treatment summary

Warm soaks may resolve this problem. Paronychia infections often require minor surgery to drain the infection. They more reliably heal if a portion of the fingernail or toenail is removed by minor surgery. If this problem affects multiple nails of the hands, it may be from repeated wetness of the hands and yeast or fungus irritation, and may require anti-fungal medicine and gloves to keep the hands dry during housework.
