Whether the first scar crosses the joint or not, be careful whether it will affect the function. Second, if it doesn't affect the function, it's just a scar, depending on how long the injury lasts. Generally speaking, if you recover in the near future, you can consider using anti-scar drugs. Anti-scar drugs are generally divided into traditional Chinese medicine and western medicine, and silica gel is a more recognized one. It is recommended to go to a professional hospital to buy it. If the time is long, the drug will have no effect after 1 year, and the child will be older. . .
