What should I do if it rains and the knife edge itches on cloudy days after leg fracture surgery?

Especially where it has been blocked, such as wounds, it will aggravate the symptoms of deep heat and lead to itching. As time goes on, some stuttering wounds will become soft, and this will stop happening.
