I too have had these symptoms for about 7 years. I was diagnosed with trigeminal neuralgia and had microvascular decompression and gamma knife surgery but neither worked. I have also been on every medications and they didn't work. They changed the diagnosis to Atypical facial pain and I was told that both surgeries were unnecessary (I had the last procedure about 1 1/2 year ago). About 2 months ago I first felt the numbness and it is steadily getting worse. The pain is also increasing and it seems that I no-longer have any relief. I am trying to remain positive but it's getting more and more discouraged. Fatima
Forgot to mention my post was on the same day as you (2/19) 12:13.
I know exactly what you're going through (thankfully, you worded it better than I). The symptoms you posted are the same as mine.
My symptoms started about 4 years ago. Since then, I was diagnosised with Chronic Sinusitis, when treatment didn't work (multiple times), diagnosised with Migraines. Of course, no change.
I went to a Neurologist who diagnosised Hemicrania Continua (you might want to google this). Symptoms matched up, but treatment (Indomethicin and Neurotin). failed.
At this point, my Neurologist has set me up with a Pain Clinic.
Are there certain triggers that set you off (mine is hormnes & weather changes).
If you hear of anything that may help , or even a diagnosis, please let me know.
Good Luck and hang in there!!!
