It does sound like you have developed some sort of viral type infection. There are many different viruses it could be, and you likely won't be able to figure out which one it is. One of the more common types of viruses that cause illnesses like what you have is the influenza virus. This is the virus that causes the flu. Typical symptoms are fevers, chills and myalgias (muscle aches). These types of things usually pass on there own. It sounds like your doctor
has already done a fairly good workup since he/she already checked your white blood cell count.
Since there are other possible causes of your symptoms, you should not ignore continued symptoms. Please continue to discuss this with your primary care physician
for that reason. Another blood test can be performed along with possibly a chest x-ray
to make sure you don't have a lung infection. A urinalysis is also necessary to rule out any infection in the urine. Most likely, you will get better in a few days. Good luck, and please discuss this with your doctor.
