Urgent, what should I do if the weather is cold and hot?

From the point of view of traditional Chinese medicine, this is generally caused by dry nose caused by weather. Some patients even have nosebleeds repeatedly, and it is easier to cure them by seeing Chinese medicine. I suggest you cook mulberry soup for the elderly (Chinese herbal medicine should go to the drugstore for consultation or Baidu, I hate to part with it).

In addition, it is best to go to the hospital for an examination to rule out the possibility of nasopharyngeal carcinoma.
