Viral meningitis is a common condition. It is also known as aseptic meningitis (although this term also includes other meningitis that is not caused by a virus). It is a serious condition that requires medical attention. I strongly encourage you to talk to your doctor
Meningitis is inflammation in the surroundings of the brain. As you can imagine, this is obviously a serious condition. However, what causes the meningitis is the real issue. Bacterial meningitis can occur in people of any age and this requires urgent antibiotic treatment. Without treatment this can cause lasting brain damage and death. Fungal meningitis (caused by a fungus) can be similarly dangerous.
On the other hand, aseptic meningitis means that it lacks the more dangerous causes. This means some viruses or medicines. This inflammation occurs, but then heals on its own. There is no need for treatment. After 4-7 days, your body with decrease the inflammation itself. There is no specific treatment.
As you can see there are major differences between the two broad categories of meningitis (there are other less common). The only way to tell the difference is to look at the fluid surrounding the brain--the CSF. This requires a lumbar puncture urgently to get the fluid.
One last point, meningitis is inflammation surrounding the brain. This must be distinguished from encephalitis--inflammation of the brain which is a more serious condition.
See your doctor. If the appropriate diagnosis has been made--then there should be rapid recovery. If not, you should urgently see your doctor.
