U r suffering from Trigeminal neuralgia......it s a neural disease.w hen nerve stimulates sudden burning and shock like facial pain occurs...

You can always take a second opinion if you are not satisfied with the treatment or the opinion of the previous doctor. Without having a look at the clinical picture and without an evaluation of the xrays it is difficult to give a rational suggestion about your problem as of now on an online platform. But the one thing that I can tell you is that your problem is chronic so you should not expect improvement within a couple of days. You already waited a lot but you still need to have patience till the time the right diagnosis is made and the right treatment is instituted and the normal healing takes its own course. Regards.
