I myself had similar complications, but was lucky enough that the restiching worked. but I did remember them talking about the drainage tube, while I was trying to overcome the experience of being stitched in my bed. I would be one of those lucky ones that had minimal damage and all my headaches have become completely non exsistent. I have some weaknes on my left side of my neck, but I am dealing with that. Most would not understand that after 10 years of migraines that being able to say "God, it is nice to have a normal headache." is one of the most wonderful things in my life.
I hope you all have luck with your extended recoveries, I know you all wish it would have fixed it all, but nothing is perfect. Be happy you are alive and can see your loving friends and families.
