Hi Edi,
MRIs are done to rule out other possibilities /explanations for your pain. They are looking for MS plaques, tumours and other abnormalities. So it’s a GOOD thing your MRI results were good.
“They” can’t say your TN is viral unless they mean you have post herpetic neuralgia ( I’ve copy/pasted an explanation of what that is below…)
There is NO known cause for TN, only “Suspected” causes…
I’ve included a list below
Medication is generally the first choice of treatment usually an anticonvulsant med.
Many people are able to live and function normally with no pain on meds.
Remissions are possible and occur for different lengths of time.
That being said TN is said to be progressive, so eventually one med doesn’t cover the pain anymore so you try 2 or 3,sometimes you only have to switch the first med to something different and that works.
BUT we are all different, we share similarities, but no two people share the same course…it is very hard to generalize with TN.
Eventually many people choose one of the procedures available that offer short to longterm success but NO guarantees. It’s a personal decision that should be made after much research and more than 1 consult with a neurosurgeon, 2-3 opinions would be even better.
I hope this helps…

Below is a list of “known” and “suspected” causes:
A blood vessel presses against the root of the trigeminal nerve.
Multiple sclerosis - due to demyelinization of the nerve. Trigeminal neuralgia typically appears in the advanced stages of multiple sclerosis.
A tumor presses against the trigeminal nerve. This is a rare cause.
Physical damage to the nerve - this may be the result of injury, a dental or surgical procedure, or infection.
Family history (genes, inherited) - 4.1% of patients with unilateral trigeminal neuralgia (affects just one side of the face) and 17% of those with bilateral trigeminal neuralgia (affects both sides of the face) have close relatives with the disorder. Compared to a 1 in 15,000 risk in the general population, 4.1% and 17% indicate that inheritance is probably a factor.
POSTHERPETIC NEURALGIA
When chickenpox is contracted during childhood, the virus that causes it, herpes zoster, can remain dormant for decades in the nerve bundles near the spine. The virus will sometimes reactivate, causing the condition known as postherpetic neuralgia, or more commonly, shingles.
In cases of postherpetic neuralgia, the reactivated virus travels around the affected nerve, causing pain. The herpes virus can affect the trigeminal nerve, resulting in postherpetic neuralgia, or pain, in the facial areas supplied by the trigeminal nerve.
