Tampons?

So I’ll be 6 weeks postpartum tomorrow. I was wondering if I could use tampons. I’ve been using pads and I’m so raw on the sides of my thighs and baby powder isn’t working. I also had a c- section which probably doesn’t make a difference, and also didn’t dilate all the way (stopped at 6cm) which probably doesn’t make a difference either, but thought I’d put that out there just in case it did.
