I would imagine that post-operative pain can last for one year. I recommend that you see your surgeon and talk to him/her about these pains.

Post-op pain from the removal of your wisdom teeth should not last that long. When they extract the wisdom teeth, they are pretty close to a facial nerve and facial muscles, so it can very well be a problem with the muscle being damaged/torn. Though the wholes where the teeth were are usually present for a long time and can become infected. I'd talk to the oral surgeon who did the extractions. Good luck.
