Hey, great result there. Ruta is listed as the most highly indicated remedy for injuries to bones and periosteum in the older repertories. The routinists today tend to go for Arnica then Bryonia, then when the bone is set, Symphytum. But as you have found out, when the indications are there, the right remedy does the job fantastically. The only thing I would add is after the first couple of days, try and pace your remedy dosages out, see if he can be pain-free a bit longer in between doses, before repeating. The remedy stimulates the natural healing ability, be careful not to overstimulate as this could lead to aggravations. Good work, you must be pleased!
