Post-rhizotomy pain?

[crankydull]

I've had cervicogenic headaches for the last two years. I had rhizotomies three weeks ago (C2/3, C3/4, C4/5 and C5/6). For the last week, the pain is worse than it's ever been-- burning and searing. The Percocet my doctor originally prescribed makes me sick when I take enough to affect the pain. I switched to Vicodon, but that isn't doing anything. The only thing that is helping is Zanaflex, which I've taken for a year in small amounts for headaches, but the amount I have to take right now puts me in a coma.

I started blogging about this whole process a few months ago if anyone wants to check it out:
