This thickened toenail has been trimmed correctly. The toes next to it need a similar straight cut. After the toenails have been trimmed, gently file the ends of the nails with an emery board to remove any sharp edges or corners that could catch on your socks. If you have a thickened toenail that's causing you embarrassment or worrisome pain, or if you believe that trying to trim your toenails on your own would be hazardous, see your doctor.
