Bnormal Pains In Her Eyes At Every Night

i need help finding out whats wrong with my girlfriend. she has abnormal pains in her eyes at night every night, which she explains as needles in her eyes. She also suffers from trembling and dizziness, thats not seizure like because she is aware , yet it affects her emotions. sometimes its a faint spell.finally she has a lymph node that has been swollen for months thats the size of an olive but not quite the size of a grape. I might add hse has had mono and swine flu but got over them both. i need to find the answer because all the doctors around here are saying shes fine, but she says theres something wrong. might i also add someone poked the back of her neck close to her skull when she was younger and that caused her to seize ( i think) and since then she supposedly cant remember dreams at night. i think anyone can vouch that when a loved one is in pain, thats the worse pain you can feel.
