Greetings, I have had atypical trigeminal neuralgia for 10 yrs. A gal in the local chapter support group for the National TN association suffers from bilateral, but hers were at different times (3 yrs apart). There are many who have had success with surgeries. Good Luck to you and remember.."You are not alone" ...as the front cover of the TN book's subtitle says.
