If the ingrown nail is deep, it should be treated in a regular hospital. The ingrown nail should be separated from the side of the nail with vascular forceps, and this process should be done under local anesthesia. After separating the nail bed, cotton or sterile cotton balls can be inserted between the nail and the nail bed, and the cotton can be removed the next day to avoid the possibility of bacterial infection and nail infection or even osteomyelitis. This operation is an invasive operation and can only be performed under the guidance of a medical professional or specialist. If the ingrown nail is not completely cured after the cotton is inserted, the best way is also to have the nail removed or treated with a nail orthotic.
