Is there a test to determine if I have trigeminal neuralgia(TN)?

Condition analysis:
No. TN is diagnosed almost exclusively by the individual’s description of the symptoms. To rule out other sources of facial pain, doctors typically order a magnetic resonance imaging (MRI) scan when TN is suspected, but that’s done to check for multiple sclerosis or a tumor that might be causing the pain. Compression of the nerve by a vessel can sometimes be seen on a MRI.

Instructions:
Compresses: Heat packs and ice packs are known to relax muscles. For some people, placing ice packs over the cheeks and jaws is said to bring instant relief, whereas others find solace in using hot packs. Still, others alternate between cold and hot packs to soothe the aching muscles. Reusable gel packs which can be kept both in the freezer and microwave and used as cold and hot packs can be used.

Soaking or bathing the affected area with hot water to which Epsom salts have been added brings relief from pain, and relaxes tense nerves.
