Hi I Was Experiencing A Pain In My Right Eye.

Hi I was experiencing a pain in my right eye. when to a optomologist he could not find anything. I went to a neurologist and he advised to get and MRI with contrast n wrote a script for Gabapentine. The mri had gadalinum. MRI was on a Thurs. took gabapentine for eye pain on that Friday. That Saturday my face went numb on the right side and I started to get massive headaches. I went to ER and they check me out for possible stroke but results came out negative. I still have massive migranes and numbness in face and can'd sleep well. any idea what this could be and what should I do at this point. this happened weekend of 12/12/15. thanks Erick
