5 months after spinal tap & blood patch. They had to stick me several times. I'm still having severe back, neck pain and migranes. What should I do?

Be reevaluated. I would certainly be reevaluated. What it would really come down to is the specific cause of your problem; which may be why they did the spinal tap in the first place. Don't hesitate to seek a second opinion, if they seen to have trouble getting a specific diagnosis. Sometimes a fresh set of eyes can be very helpful.
