Can gabapentin for i c cause pain/swelling on area of 3rd-5th toes where toes meet with top of foot, one foot only?

Probably not: Gabepentin can cause swelling but not usually that specific of an area. More likely there is another cause like trauma or an infection. I would have the area looked at by your favorite podiatrist.

Unlikely: Gabapentin is usually used to ease your pain not to cause it.

Not usually! : Gabapentine is an effective treatment for neuropathy and other nerve injury. Swelling in the feet is a possible side effect but pain and swelling in a specific area would more likely be something else. It could be an injury, arthritis, hammertoes or stress fracture. You need an evaluation by a medical professional. .
