what causes hot and cold symptoms
Symptoms of a common cold usually appear one to three days after exposure to a cold-causing virus. Signs and symptoms, which can vary from person to person, might include: Runny or stuffy nose. Sore throat. Cough. Congestion. Slight body aches or a mild headache. Sneezing.
A hot flash begins as a sensation of intense warmth in the upper body, followed by skin redness (flushing), drenching perspiration, and finally a cold, clammy feeling. Typically, these symptoms begin at the head and spread downward toward the neck and chest. They last from 30 seconds to 5 minutes.
