For the second part of your question...

Health and balance (not over training). I don't think you need to look at brittle bones directly. I mean that would be a symptom of imbalance. You don't treat brittle bones, you bring the body into balance, homeostasis and grow in health.

Some other angles on healing-take it or leave it or do what you want...but if anything seems to fit might be an idea to consider..

Bones, skeletal structure, adrenals are connected also mental lathargy and incapability of inner stillness (mind races)..
possibily safety/security/survival stress and or family stress

If those seem to fit for you then you could look at approaching the healing and symptoms multidirectionally.

Another angle of possibilities is..with the itself is..
get many sore throats, neck aches possibily, thyroid or asthma issues...
possibly bocked creativity, perfectionism or inability to express emotion

If either of those seem to fit or both do then it can be wise to approach it from a few different angles.

When alright I think would be best assessed by someone who can check out out and knows something about that area more directly in terms of healing completely etc

Different ancient systems look at the body as a whole and even when its a clear acute trauma there can be issues around it that made it weak or connected to it that could limit healing (some people go a lot further on the connections)

In any case I wish you well in your healing.
