Stitches advice

I gave birth 6 days ago and was wondering if anyone had any tips and tricks thats helps/helped them use the bathroom post birth.

Im at the point where im physically holding in urine just because im scared to go. Currently its been 18 hours.

Ive tried using a spray bottle, salt baths and lavender and milk baths and the pain seems to only be getting worse and not better. My midwife took a look at them at a home visit and wasnt concerned. Help me😂
