My left jaw and mouth are burning while using computer and mobile. What is it?

Hi doctor,

I think that I have atypical trigeminal neuralgia (TN2) and started taking Carbamazepine from two days back. It seems to help me. But it is not helping me entirely. Constantly, I have a dull ache in the left jaw area and a tingling or burning sensation on the lower outside portion of the mouth. My condition gets triggered by computer and cell phone lights. As soon as I see my computer, I have a feeling of pulse within a minute. When I see a computer for a long time, it irritates my ache and I have a mouth burning. But my pain is not severe. It is annoying and it causes massive inflammation in my face. While avoiding using electronic items, my ache and burning goes away. I am not sure about my health condition. But it seems to be challenging to my work. Do these LED lights trigger my trigeminal nerve? What is the solution?

Thank you doctor,

When I prevent having a computer and phone lights, I seem to be fine. I have tried turning my computer to night mode as well as wearing axon optic glasses. But still, I feel the pulse. Now, I am wearing an aluminum foil mask to prevent having light coming from the sides or on the edges of the glass. It seems to help me slightly. You have mentioned that bright light indirectly inactivates trigeminal nociceptors, but sun does not trigger my pulse as computer and phone lights. I am willing to see a neurologist soon and do an MRI. I want to know whether Capsaicin help in treating trigeminal neuralgia.
