In adults, fever
is a less reliable indicator of a viral infection. In children, practically every time they have a viral infection they will also get a fever. However, in adults, most viral infections are not accompanied by any real fever. One exception to this is influenza, or flu, which almost always causes fever. However, the common cold viruses that are the usual culprits often do not.
The fact that you had nausea and achy muscles for a few days is also quite typical of a viral infection. These might be the only symptoms you develop, or you may also develop some cold symptoms over the next few days.
Most of the time, these infection don't require much in the way of medicine. Make sure you get plenty of rest and that you stay well hydrated. You can take the usual over the counter medicines, such as tylenol or ibuprofen, for the achy feeling. You should be feeling better within a few days.
If the symptoms worsen significantly, of if you start to have high fevers, then those might be signs that you need to set up a visit with your primary care doctor
to make sure there is not something else going on.
