I've got a question about how to proceed, medically speaking.

I was involved in a car accident on December 30, 2007. I suffered trauma to my neck, which I have been dealing with for the past year. I have been on so many different cocktails of medications, have gone to physical therapy two to three times a week, and have started getting nerve blocking shots regularly. These are my questions:
1. How long would you give physical therapy, nerve blocks, and medications to work? By work, I mean no more headaches and neck pain is a 1 or 2 on a scale of 1 to 10.
2. At what point would you consider surgery? This is the last option as far as I’m concerned. The neurosurgeon would put a plate at C3 and C4 and permanently disable the occipital nerve.

I know that this is a complex issue, and I am surely not asking for medical advice, only personal opinions about where one might go from here. It’s been just about a year now. I woke up on Christmas morning greeting with a terrible pain in my neck and a blaring headache. Something has got to give.

Merry Christmas.
