Hi there. I am a certified homeopath and really recommend the use of Arnica as well. If you have the ointment use it as often as needed. It would be best if you can get Arnica for internal use - in a 200c potency. If you can only find a 30c potency then put 3 pellets in water and sip throughout the day - shaking the water bottle before each use.
If you find it is broken then you can take a dose of homeoapthic symphytum after the bone has been set.
For severe pain that makes you not want to move the foot at all, when even the slightest movements hurts and you don't want anyone touching it at all try homeopathic Bryonia.
