Ah I see, well the feet will need to be treated to heal before much else - that's the primary thing the NHS will look at right now.
How many fractures have you had? Fingers, toes, limbs, the lot. I'm 39, broken all ten toes and ten fingers more than once, one wrist, one thumb separately, and a foot repeatedly. That I know of! And tbh, apart from the foot, I knew exactly what I did to cause each break. My mum on the other hand, has broken both ankles and her femur without knowing how, broken a rib and a vertebra coughing, her wrist twice in minor falls.... The list goes on with her osteoporosis fractures.
If you are osteopenic or have osteoporosis, it's looking at long term prevention strategies to reduce your chances of additional fractures.
Do you have a high calcium diet? That's an important thing. So is weight-bearing exercise (even just walking). They help build healthy bones.
Crunching and cracking from joints, back, neck etc tends to be the cavitation noises from synovial fluid rather than bone on bone unless the back is seriously deteriorated.
