Gabapentin is typically used to treat nerve damage and is a non-narcotic pain medication which means it's used as the first step a lot of the time with injuries such as neck or back which are the most common. It's the cheapest medication available as well so insurance companies usually want prescribers to try the cheaper alternatives before taking the next step with other meds. Other possibilities are things like Lyrica but it's a much more expensive pill so you have to really explain your situation and hope they take you seriously and hope your insurance company is in a generous mood....
Personally for me Gabapentin doesn't have any effect.
