Inguinitis is an inflammation that occurs in the nail groove and its surrounding tissues. When trimming the nails, you should avoid trimming too short, keep the nails rounded, and cut the nails that are growing towards the nail groove in time. 1. Avoid trimming too short: If the nails are trimmed too short when trimming nails, the skin at the distal end of the nails will be easily squeezed during daily hand or foot exercises, and the skin may be irritated during the growth of the nails, which may cause skin lesions and infection. Therefore, when trimming the nails should pay attention to control the length of the nails, in order to prevent trimming too short. 2. Keep the nails rounded: when trimming nails, try to keep the nails rounded, so that both sides of the nails are higher than the skin, reducing the chances of nail growth towards the skin. 3. Cut the nails that grow into the nail groove: If you find that the nails have a tendency to grow into the skin, you should cut the nails in time to prevent the nails from piercing into the skin, causing breakage and inflammation. If the situation is more serious, there has been obvious redness, swelling, pus, in the nail trimming at the same time, you can also go to the hospital to check, cooperate with the physician for specific treatment, so as not to delay the condition.
