Alegar,
I also had the spasms, they lasted 6 weeks after surgery. I was usually fine until around noon and then I had the spasms until bedtime. The only relief came when I laid down in bed, so I learned how to download movies and watched more than I care to admit, lying in bed. I took no meds, (doctor said no) then after 7 weeks I woke up one day and they were gone, what a relief.
I suspect this delayed my improvement in the continence department as everytime I did a kegel it would bring on spasms so I had limited improvement.
Hope all goes well and the spasms disappear.
