Is it post op day 2 ?

I had surgery on Monday to remove a golf ball sized bladder stone. Tuesday, I seem to have been peeing so I went home.  This morning I could not pee, or stop the bladder spasms, so I went in to see the surgeon.  He put the catheter back in.  To be in place until Monday. It feels as if I have to pee constantly. Thanks to all of you who sent your well wishes.
