Remedies for recovery down there after vaginal birth

I had a vaginal birth a week ago with no major issues, a small first degree internal tear but otherwise no complications. I still find it down there incredibly sore and ‘raw’ and was wondering what you have used to help with the recovery? I still can’t walk much more than 100m maybe and when I stand for longer than a minute it’s quite uncomfortable, and even lying down I can still feel it.

So far I’ve tried tucks witch hazel pads, sitzbath spray, icing it and tight underwear but none really seem to help and I find the tight underwear is actually making it more painful.

Looking for other remedies that helped you speed up recovery. Thanks
