Ibuprofen not working anymore?

La

So I’m 3 days PP! My dr is having me alternate between Tylenol and Ibuprofen every 3 hours. I’m obviously in pain still but I’d feel good enough to do things and just enjoy PP. well today, I started feeling hardcore stinging not sure if it’s just from vagina or my stitches (2nd degree). I’ve been doing everything how they instructed me to at the hospital: peri bottle, dermoplast, tucks. It stings so bad and my meds aren’t helping at all!!!!! Anything else I can take to help get rid of the pain? I’m suffering. And to think it’s barely day 3 of recovery 😔
