Well, it took me longer to post than I had anticipated; my apologies. The neuro is convinced that my occipital nerve is being irritated somehow. He believes one of three things is happening: there is still some swelling that is pressing on the nerve, there is scar tissue growing aroung the nerve, or the nerve was damaged during surgery.
I'm on gabapentin (sp?) for a few weeks to see if it can relieve some of the pain (it hasn't) and after that, we'll discuss other options. Basically, the options are either live with the pain or surgery. If there's scar tissue they can remove it or possibly reposition the nerve. If it's a damaged nerve, they can sever it (yikes!). That means that the entire back of my head will be numb forever. And, even if they do that procedure, the end of the nerve that is left can also become irritated and I'll be right back where I started.
So, for now, it's a waiting game. I just wanted to post what my neuro had said in case it would help any of you with similar problems.
