Advice please?

My suspected leak began July 5th from a epidural steroid injection at c7/t1, followed by a chiropractic manipulation. I've had x-rays, CT scans, MRI's with and without contrast. I've send those off to Cedar-Sinai along with the rest of the application paperwork. My local neurologist has me scheduled for a lumbar pressure test, CT myelogram, with a blood patch all in the same procedure next week. I'm concerned about having the lumbar puncture and blood patch on the same day. The NP also confirmed that they will only do a targeted or blind patch in the lumbar area, and so the odds of it patching a cervical or thoracic leak seem slim to me. Would you go ahead with this procedure, or cancel and just continue to wait on Cedars to respond? I also have bone spurs around where the original injection was, so it may be a surgery situation ultimately.
