My we assume they've done an MRI within the last couple of months? And my neurosurgeon has called for a lot of diagnostic tech prior to the surgery. EKG, PTT, chest x-ray, urinalysis, a raft of blood tests including A1c (I'm diabetic). They should be doing the same for you.
2 MRI’s in the past 6 months. Last was 3 weeks ago. My A1c is 5.
