TRIGEMINAL NEURALGIA--- Radiography treatment

I am reaching out to seek your advice regarding my ongoing struggle with trigeminal neuralgia. I had microvascular decompression (MVD) surgery eight years ago, but in the past 5-6 months, I have been experiencing significant pain again.

We have consulted with neurologists in India, and taking medicines since last 5 months but there is no use with that medicine, they have recommended radiography treatment. I would like to know your opinion on this treatment option. Are there any alternative treatments available that might be effective? Additionally, if we decide to proceed with radiography, what potential side effects should we be aware of?
