bone broths should help a fair amount as they have a lot of nutrients.
without LHT, I'm not entirely sure. But, if you'd like, we can have a skype, talk about what is going on with you, and I might be able to create a quick (10 minute) yoga routine that could help bring in some movement which helps build muscle (as well as flexibility) which can help with bones as well.
It will be free of charge for a vet, ok? Anyway, yeah. If you want. send me a pm.
