Side effects of gabbapentin or TN?

[Jen2510]

I have TN. I am on 300mg gabbapentin four times a day. It only lasts about 4 hours at a time then I get breakthrough pain. It always starts with a horrible headache then it goes to numbness in my cheek and  jaw and ear. The other day I had a new symptom that was a sore throat pain in underneath of jaw and behind my ear. Anyway, someone told me the headache was a side effect of gabbapentin but the headache has always been present even before I started medication. The headache is constant and unrelenting.
I have had MRI and cat scan and they were normal. Dr thinks my TN came from mastoiditis that I had. I also had a fall where I fell and hit the right side of head.
Any insights on headache and tn in general. Any help would be greatly appreciated.

I have been on Gabapentin for over a year now, other than sometimes feeling tired or a little "uplifted" (I guess you can experience some euphoria sometimes)... I actually do not experience a headache with Gabapentin. In fact, it has actually helped with the chronic migraines I have. Right now, I've got something going on with TN or Bells Palsy or something and I have severe pain... but it's pain that goes from my throat up to my temples and I do have a headache, but I'm also on a ton of medicines. So I'm thinking it is from the pain or from the meds. :(
