Suppositories for hypertonic PF pain relief during sex

Has anyone tried these? Any recs? I've tried a lot of things including PT, continued stretching/yoga/breathing exercises and lube... all kidna work but nothing close to 100% - I'm 8mo postpartum and things seem to be getting worse so definitely am partly in my head about this (to say nothing of hormonal changes etc), so welcome even a placebo effect!

I know things get stretched out a lot during pregnancy, plus I was doing perineal massage a few times a week before birth. Had an uncomplicated birth and recovery and am quite active so almost wonder if everything snapped back into place too quickly..
