I had an emergency MMA because my 4th CT scan showed increased beeding. I had the scan at 10 am, was in my car driving home and was called by my Neurosurgeon to go directly to the ER! There was no anesteheadiologist available that day so I opted to be awake during the procedure. I had heavy pain meds in my IV. It took about an hour, was not painful and I was in the Neuro intensive care unit over night. I did have a head ache but not terrible. The pains on that side of my head continued for about 2 weeks (and I had sore teeth on that side of my mouth off and on during that time - maybe due to a nerve being effected during the procedure?). It's beeen almost 6 weeks and I am pain-free. Another CT scan is scheduled for next week.
