My surgery was for a 4.5cm AN, and I've definitely had my share of issues. However, I wasn't really surprised, and the recovery took time but the post op was NOT as bad as I had imagined.
I was a little suprised at the MRI, I had a day before the surgery. They put small "magnetic stickers" on my face that I needed to leave on until my surgery.. This helped them correlate my head to the MRI image for the surgical procedure. So nothing negative.
The advice the worked for me:
1. You will be on high dosages of steroids, after the surgery, to control the swelling. Plan on an ultra low sodium diet. This will help minimize water gain and worked well for me.
2. You will have liquid steroids in the Hospital and switch to pills when you go home. During the switch from liquid to pills, you may get a few symptoms. For me this was sweating and hot flashes. Also, as you ramp down on the pills you will also have some symptoms. No big deal.
3. I was off the pain medicine (and Tylenol), five days after my surgery. I was NOT pain free, but I liked being less dopey. However, pain medicine in the hospital is AMAZING. Goes right into the IV..
4. Start walking immediately in the hospital. Walk as much as you can. It won't be pleasant.. vertigo, tiredness... Push yourself. The vertigo is a false signal (or lack of signals) to the brain. Your brain should learn quicker if you are more active.
5. No lifting more than 8 lbs for the first couple weeks.
6. Sounds funny. Eat foods that won't have you "strain" on the toilet. Pushing to hard can cause complications.
7. I loved "grapes" during my recovery.
Lumbar drain??? Sorry no experience.
