Pinky,
Just keep in mind that the surgery doesn't heal you immediately, it only stops the spasms. So right after the surgery, you are super sore from the trauma AND your fissure is still gonna hurt. Please understand that, and it will keep you from despairing.
My CRS told me I would feel like killing him for about two weeks after the surgery, but actually, I only wanted to murder him for a bout a week!
Hang tough!!
