I had a total knee replacement on Jan 2, 2007. My knee still hurts like the dickens and is still swollen ( which seems to be par) and gets so stiff at times, My surgeo presecribed gabapentin. Is this medicine good for what ails me? Please let me know before I confront him, He says I'm doing great, but he doesn't know the paid I suffer every night. Daytime is not aa painful at nighttime,
