Lifelong?

Iv had PVP and sciatica and diastasis recti which is contributing to the pain as my core muscles arnt supporting well etc. I’m now 34 weeks and it’s got so bad I’m having moments of physically not being able to walk. The pain of walking putting one foot in front of the other can be agony but then other times not so bad. I’m starting to worry about long term effects of this and feel my pelvis surely can never recover fully from this. Anybody got advice for long term recovery? Iv got a physio who has given me lots but doesn’t really help - the belts don’t seem to work as I’m not on my feet long enough for it to be worth putting on and off every time. I’m also scared for birth and how this will impact that - I can’t really open my legs for long!
