I have nerve injury in my jaw due to the removal of a wisdom tooth.  This was 20 yrs ago.  I have had two surgeries and radiation on my nerve. .I am presently on LYRICA 50 AM , Lyrica 100 PM and Topomax 50 mgm pm.  Recently I was put on Methylprednisolone,, Advair,Spivia..My mouth is on fire especially around my nerve injury.  What is doing this?VERY painful.
Thank you for the query. I am sorry to say that after 20 years of injury to your nerve it is almost impossible that you will have your nerve totally repaired. It's good that your doctor have tried with surgery and radiation. You have to continue with your LYRICS and TOKOMAK. Please keep in touch with your doctor regularly, as these Chat Doctor.  You can consult your physiotherapist for any help. You can also think and consult about some alternative management like Biofeedback, Acupuncture, Trans-cutaneous electrical nerve stimulation(TENS) etc. These alternative managements have reports of some excellent results. Hope for the best.
