Last night was great

Last night my bf and I had the best sex ever. To the point where when we were done, we just collapsed on each other, and our legs and arms were weak (not to mention he has scratch marks all over his back, and bite marks on his chest 😂). But anyway, today I'm really sore. The backs of my thighs and butt, and uh down there. Is there any way to get rid of it or lessen the soreness without medication? I can't take any painkillers because of my stomach-doctor's orders.
