anybody have any advice on peeing over stitches?

Ma
I had over 30 internal stitches and they were so bad and raw that I had to go back to the hospital to get a catheter put in for 3 days.. 😔😣😭💔 I had to take it out last night and peeing is AWFUL.. Absolutely terrible. I didn't have an epidural and this pain is worse than birth. 
I've tried dermoplast, squirt bottle, pain pills, cold bath with an ice pack.. Can anybody help?.. I'm basically desperate 😫😭😭😭😭😭 I can't take this anymore
