...do what the physio tells you, when the physio tells you or suffer the painful consequences later
I've still got the carbon fibre cage and titanium rods n screws holding my spine together and my ribs have all been cut'n'shut to fit my smaller chest cavity so they've still got the wire holding them all in place. The spinal fittings will always be there, even though they're rubbing on my shoulder blades, the rib-wires are staying too, even though they feel like they're digging into the muscles alongside.
I suppose the moral is, don't be a muppet in the first place, but when you do, get the best opinion you can afford (yes, pay for it if you have to!) and then make sure you LISTEN TO THEM
