Hello, The swelling you noticed is called edema and is a common side effect of Gabapentin. It is unlikely to be associated with brachioradial pruritis or arthritis of the spine as they come with their own set of symptoms. Gabapentin drug, based on its dosage can cause some amount of fluid retention resulting in this swelling of the hands and feet. It is not an emergency. Do not stop cold turkey with your medication as it is an anti-convulsant. You could consult with your prescribing doctor to reduce the dose or add a diuretic. Additionally decreasing your salt intake will also help. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Pranav Balakrishnan
