Doctor, did I get hurt, not a gray nail? I'm afraid
If you wear too loose socks, it may be appropriate to avoid injuries. If you wear too loose socks in the near future, you may be able to recover from injuries. It is recommended that you wear too loose socks as much as possible. If you have a history of severe injuries, you may not be able to recover from injuries!
At present, there may be congestion under the nail caused by trauma, rather than gray nail. Don't worry too much. If the toes are squeezed at ordinary times, the same symptoms may occur. At present, there are no uncomfortable symptoms, no treatment is needed, and health will not be affected.
