6 weeks ago, tooth pain started on my upper jaw and facial pain on the left side. The pain lasted for an hour and it went away. For 5 consecutive days, the pain continued. Its the most painful pain I have never experienced. I take pain killers but didn't help. I went to three dentist but all of them ruled out dental problem. Then I went to neurologist and did mri. Based on the result, the doctor said it could trigeminal neuralgia but told me the cause is unknown. The mri result shows all is normal. The doc prescribed tegrital 200 mg per day. My condition started improving after taking tegrital. After taking the medicine for 20 days, I had pain only for 3 days. I went again to see the doc for a check up and the doc suggested to continue using tegrital for another 6 weeks. Yesterday I have severe pain again. I am still taking the medicine. I do not know what trigger the pain. My question for you, 1. Is this a serious illness? 2. Will it go away on its own? 3. What should I do?

See don't worry it will go ,it's not a permanent disease, it is curable, actually every disease has its trigger point for that doctors you met have they asked many questions means about the pain how, when,were it occurs and many things r asked, so if you you have any doubt you can consult me frankly so that I help you to find out trigger point.

Trigeminal neuralgia is a unilateral disorder characterized by brief electric like pains, abrupt in onset and termination of one or more divisions of trigeminal nerve. Pain is commonly evoked by trivial stimuli including washing, shaving, smoking, talking and/or brushing the teeth (trigger factors) and frequently occurs spontaneously, small areas in the nasolabial fold and/or chin may be particularly susceptible to the precipitation of pain (trigger areas). The pains usually remits for variable period. The cause of the majority of cases of tn remains controversial, but approximately 10% of cases have detectable underlying pathology tumor of the cerebellar pontine angle demyelinating plaque of multiple sclerosis vascular malformation the most widely accepted theory is that a majority of cases of tn are caused by an atherosclerotic blood vessel (usually the superior cerebellar artery) pressing on and grooving the root of the trigeminal nerve. This pressure results in focal demyelinization and hyperexcitability of nerve fibers, which will then fire in response to light touch, resulting in brief episodes of intense pain.

I think it's due to infection, your taking medicine for that, it will be fine once infection is goes off, so don't worry.
