I’m really sorry, this sounds incredibly frustrating, especially when running is the one thing you enjoy and it feels completely off limits!
One thing that really helped me (and that I wish had been explained earlier) is that pelvic floor rehab usually isn’t just about squeezing harder or holding for longer. For a lot of people, especially when symptoms are severe, the issue is how the pelvic floor is working with the rest of the core and breath, not strength alone.
Doing the same long holds over and over can sometimes make things feel worse or just stagnant. What made more sense to me was working on different tempos (shorter holds, quicker lifts, full relaxations - this lady on TikTok does a great job of showing the variations: www.tiktok.com/@femalephysiosarah) and learning how to engage the deep core so the pelvic floor isn’t trying to do everything on its own.
An internal assessment can be really useful for this, not just to check strength but to see whether you’re actually able to fully lift and relax the muscles. It might be worth asking your physio about this next time, especially if things feel pointless at the moment.
It’s still very early days with physio, even though it doesn’t feel like it. A lot of people don’t see meaningful change for weeks or months, and that doesn’t mean it won’t happen. I also found having a simple, postnatal-specific plan to follow at home in between physio helpful as it doesn't just do squeezing but rehabs the whole core, pelvic floor etc. This is the one i used: https://wild-mama.co.uk/
