Hot flashes and nausea are most commonly caused by hormonal imbalances in the body, most notably, by sex hormones. For women, a decrease in estrogen is often to blame, whereas in men, testosterone deficiency can create the problem. Sometimes, the symptoms occur for reasons not related to those hormones at all.
If you have a cold, youâll probably experience symptoms such as: 1  runny or stuffy nose. 2  sore throat. 3  sneezing. 4  mild-to-moderate fever. 5  cough. 6  headache or body aches. 7  mild tiredness.
While the common cold and influenza share many clinical features, acute cold symptoms typically appear gradually over one to two days, whereas influenza symptoms (high fever, severe muscle aches, dry cough, severe headache) are typically more severe and abrupt in onset, often developing within hours.
