The whole process of nail trimming for onychomycosis is as follows: trimming the front of the nail, cutting the ends of the nail, grinding the edges of the nail, and pulling out the nail if necessary. 1. Trim the front of the nail: the nail should not be trimmed too short, but can be slightly over the nail bed. Trim your toenails horizontally with flat nail clippers. 2. Trim the ends of the nails: Trim the nails near the nail crevice with a beveled nail clipper. Trim both ends, trimming a rounded curve, not too short, and keeping it flush with the skin under the nail. If the nail grows toward the nail groove, cut it off in time to avoid ingrown nails, or the nail groove inflammation may recur. 3. Sharpen the edge of the nail: Sharpen the nail with a nail file to make the edge of the nail smooth. If you are diagnosed with onychomycosis, you should take anti-inflammatory drugs such as amoxicillin to treat it in time. If necessary, you should have your nails extracted and treated with medication and nail extraction under the guidance of your doctor.
