Palsy by itself, as I understand it, means "paralyzed." So this means that your disc is paralyzed? I've never heard of such a thing.
And I've NEVER heard of a disc having palsy. I'm wondering if your doctor isn't handing you a line of whatever because he doesn't know what's wrong!
I might be totally wrong, and i'll certainly ADMIT it if I am! LOL But with the years of research I've done, I've never come across this. Maybe my eyes are failing me.
It sounds to me like you have some inflammation & swelling going on, and that's what is pinching some nerves. Granted it would take a couple of months for this to take care of itself, but it would help to have some medication to help ease it. I'm SURE you have swelling in there - that's unavoidable, after surgery. Make sure you use some ice periodically. Use it for 20 minutes every 2 hours, and that should help with the swelling & inflammation. It should help with the pain too. My Neurosurgeon taught me this when I had surgery.
Anyway -- best of luck and I hope things work out well. God bless. Hugs, Lee
