I had this issue (PNE) on right side somewhat before surgery. Due to long bike trips on a hard seat, plus lots of long sitting at I.T. jobs for thirty years. (I think these were the causes). I never got a firm diagnosis of PNE, but I am really sure it's what I had.
But it ramped up big time after the surgery. Interesting what Gear said about
operating tables. Could be...
I finally located a type of cushioned pillow made exactly for this. Choose the appropriate one for your weight. I found they lasted about
6-8 months of daily sitting before the foam squashed down enough that the pain would come back. So I would reorder.
/www.icnsales.com/chair-cushions/The covers are removable for occasional washing. Now retired, I still have one in my car seat to drive, esp. for longer trips.
Also, started biking again about
three months after RALP. I bought one of the bike seats that has two separate pads, one for each butt cheek, with about
1-2 inches between, so there is no pressure on the pudendal nerves or groin. That helped a lot, too. I think this was the source or there are others like this on the web--you get the genera idea:
