DM's at the stage in life of niggling problems. Condition 1, has spent years cycling around the GP, physio and gynae. She should have had surgery for it about this time last year but it was cancelled the evening before just after she'd got the cats into the cattery. She still hasn't had it as when she got a new date in early March, she was still recovering from another issue that had her in hopsital, plus that nasty "chest infection"...
It took years to get her knee replaced... too young (60s)... try physio... you're getting a bit old now (70s)
I had issues with the physio system in pregnancy. The GP said at 34 weeks that it was "pregnancy aches and pains" that I was rapidly losing the ability to walk and could no longer face the burning agony of getting around the supermarket and was pretty much housebound a few weeks later unless I was driven and dropped off door to door. Second time, I got the MW to refer me to physio at about 24 weeks as my pelvis was begining to creak again. About 31 weeks when I made it to "group physio" and about 36-37 weeks before I got a 1:1 appointment and able to get aids... I turned up on the crutches that I'd already aquired and as DH was away that day would have had to cancel with out those as I couldn't have walked from the car park without them to get to the appointment to get some 
I'm absolutely not against physio, used properly it's a valuable tool, but the NHS rarely uses it in a timely, efficient manner. Usually as a delaying tactic.
I'm pretty convinced that knowing about the SPD second time and knowing how to keep mobile saved me from a minefield of the extra niggles and complications that I had in DS1's birth. I kept a stone, mainly of fluids off and avoided carpal tunnel syndrome and was able to labour inna better condition. First time I ended up in HDU for 36 hours and I think the poor condition I was in, weighing 50% more than I had 5 months earlier and barely able to bear my own weight on my feet was a significant factor.
I wish the NHS would be more smooth and joined up in its processes rather than cycling patients around until only the drastic action is left.
I was working in a hospital when New Labour did overtime "initiative clinics" to work through the waiting lists. It was expensive paying everyone generous overtime to incentivise it, but for several years, it paid off long term by making treatment times more reasonable.
Capacity hasn't kept up with the population (and that's fed Brexit. That's a strategic error of managing population change, not an individual issue)
