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.
Flu vs. Cold. There are differences between the flu and a cold, say local medical experts and the Centers for Disease Control and Prevention. The biggest difference is that with the flu youâll usually have a fever (100.4 degrees or more) coupled with muscle pain and body aches, which can be severe. With a cold, youâll have more symptoms like sneezing, a cough and phlegm, said Dr. Amanda Porro, director of Nicklaus Childrenâs Hospitalâs pediatric care center.
