I had botox into my right (worst) side piriformis muscle and it did work a treat but mainly for the constantly tight, and sometimes tighter (evil thing!) p muscle.
I couldn't say that the nerve pain was massively much better, maybe a bit, but the muscle pain definitely was. The piriformis muscle is (almost definitely) where I am entrapped.
I possibly expected the huge chunks of numbness to be gone. Especially the bits that get more painfully numb ( I know! how
can that happen??) with 'activity'
Have to laugh when 'activity' actually means sitting still too.
I would hope that because PT has given you some relief, the botox may well give good results. I have to say that for me physio (PT) didn't work. The only thing that gave any good pain relief was botox. The theory being that with me, scar tissue developed after a fall and subsequent haematoma which manifested itself as an egg sized lump ( more of a quail's than an hen's)in my p muscle. Didn't have a clue then that there was a piriformis back then of course.
Hopefully this will be the difference. It has been noted by a number of doctors who do know their stuff, that a 'traumatic' onset is more likely to be entrapment and PNE, while PN sufferers can find that conservative treatments work well.
I guess the other thing to try would be a pudendal nerve block, although if they already know that the tight pelvic floor muscles are the cause. . . . .??
Other things that might be worth a try,
cognitive behavioural therapies and mindfulness. . . . . really can help.
Hynotherapy

I really like the pelvicrehab site; even though I'm pretty sure my pelvic floor is not a problem. They just talk such sense.
I have heard people talk about muscle relaxant vaginal suppositories. I have probably put that all wrong as I have not used anything like this, but thought it may be worth mentioning. Hopefully someone else will tell it more correctly or you could research it if thought appropriate.
I did see this but you possibly have tried already;
Relaxing the muscles in the pelvic floor area overall is important, and warm baths or hot tubs twice a day can be helpful. In addition, low doses of muscle relaxants such as Valium (diazepam - 2 mg three times a day) may be helpful. from

They also suggest yoga and a good posture, who knows?? standing up straight can't ever be a bad thing.
Just don't do kegals!
and take care,
