on the outside of your stitches and/or perineum area. its a numbing spray and has really been helping me. I use it with the cold pads. I get better leverage when I spray it while still on the toilet cause of where my stitches are located. and if you still have the water bottle they have you to squirt keep using that after you use the bathroom and remember to only use the tissue to pay dry and not wipe @jadon
