I have been taking Gabapentin
300mg 3X daily for one month for severe neuropathic pain and
CRPS (ulnar nerve) and
it is very effective managing pain. However, the side effects significantly affect cognitive function.
Change in balance, unsteadiness, loss of coordination, inability to concentrate, unable to focus, dizziness, nausea, drowsiness, tiredness, change in vision (blurred/double vision), rolling eye movements.
