Fybro and fractured bones

When I went to A&E, with a moaning husband four hour wait for just a sprain, they only x-rayed the ankle said I had a nice clean fracture put it in a temp cast, go to fracture clinic next day and they'd put it in a full cast. Well the consultant took one look and sent me for more x-rays of my foot, sure enough that was fractured too, he told me then that it was in a place notorious for not healing. A week later, new x-ray, same consultant, said the fracture had moved and he wanted me to see a surgeon, so a few days later met the surgeon, after shaking my hand his first words were you've done a right one on yourself, he then told me I would get arthritis in both fracture sites as both went through the joints and that he needed to put a screw in the metatarsal as the gap was far too large to ever heal, oh and that later the screw would have to come out. So I knew it could be a long process, most of the trouble I have is trying to work out if the aches and pain are the result of the fractures or just normal fybro. Thankfully had a chat with the physio, who says she hears this a lot, and that she thought fybro sufferers who have fractures suffered far more pain. Trouble with doing the physio exercises is they tell you pain is your body telling you you've done enough, but I'm having trouble telling what pain I've got. If you get my meaning.

I had an accident back in 2008 and managed to fracture several major bones, tibia was completely severed and ground to pulp in one place.  I had various bolts, plates, etc etc.  It took a couple of years before they would remove any.  They took about a dozen bolts out and one of the plates and the ankle joint was a lot more flexible and a lot less painful.  Couple of christmases ago I fell and broke my metatarsal.  This time round just a cast no scews etc., but I did get told it would be at least a year before it had grown back at all, due to my age and being post menopausal female, our bone density can be very poor and new growth is very slow.  Added to all this, I paid out several thousand pounds for extensive dental work including an implant. I had BIOS material implanted to try to grow new bone then the implant, which never did take.  Unfortunately I'm one of those people who just doesn't heal well and new bone growth is almost non existent.  On the subject of differentiating the pain - I now have severe OA in that ankle plus OA in both thumbs and most of the time that pain is quite different to the muscle pain of fibro, although there are days when it's all flaring up and it sort of all melds into one whole body 'hurt'.  One thing i can say is that exercise, even very gentle movement is ESSENTIAL to help the healing process for broken bones, otherwise they seize up completely and its far worse.
