I was diagnosed in 2015 with TN2. Had all the MRI's, MRA's.  In June 2016 I underwent Gamma Knife Radiosurgery.  The pain resolved for a short time.  Ended up going to pain management and acupuncture. Very costly. Now I have constant numbness and tingling. Called the neurosurgeons office.  Inquired if the numbness could be from the Gamma. They stated not that many months after. You need to get an MRI.  So I go to my Neurologist.  The MRI was completed.  Had an appt with the Neurosurgeon, who was not very professional. He said "I think it's fom the Gamma". I said then why did your nurse tell me it couldn't possibly be. His response was unprofessional. Said I will have to continue with pain management.  Sorry I can't help you." Then he tells me I have a tiny Meningioma in my head, but not to worry.  I said easy for you to say.  It's NOT IN YOUR HEAD. I thought well maybe it's my teeth. The xray showed what the dentist called an abscess. I was never so happy.  Finally I have an answer. Went to the Endodontist two days later. Nope, Xrays he performed showed no evidence of infection.  My heart dropped. So sure it was my teeth. I'm going for a second opinion this week.  Just wondering if anyone else has the numbness and tingling?  I can't live like this.  I've been off work for almost a month because of it.  I'm so depressed.
