Hi, I am 32yr old male; height 6 2 ; weight 220lbs. I have been prescribed Neurontin 600mg 3 times per day for headaches. Over the period of 3 months, the medicine has stopped working and I am left with the same symptoms as before, which are: numbness/sleep feeling on top of head that can extend down to both eyes, bridge of nose pain/pressure and drainage from my ears. What else can I do about this? I have been to the ER and had CT, MRI of my brain and sinus scan but everything is okay. Since neuortin is a nerve pill --- could this issue be with a nerve being pinched in my neck/back?
