Dear Andy,
I assume that your toes were not displaced by the injury (leaving them off at a strange angle), and that only the toes (ie not your forefoot) were injured - in which case you should have healed fully in the time for your Camino. Broken toes, fingers and ribs that aren't displaced and are otherwise uncomplicated, are not X-rayed, because it doesn't affect the way they are treated. This is because there are very strict rules about exposure to radiation enshrined in law - but it also gives us clinical staff the opportunity to say 'ha ha ha - there's nothing we can do about it...go home".
I'm only kidding about the last bit, honest.
The treatment is rest, ice, elevation, anti-inflammatories (like ibuprofen, if you can take it), and 'buddy strapping' - or taping with fabric or other medical tape (always with gauze or cotton wool between the toes to stop the skin chafing) to the adjacent toe. Do this as often as required (when the tape gets wet or grubby) and for as long as the toes are painful (most people give up after a week or two). Wear good supportive shoes, and they should be healed in about 4-6 weeks.
You can't really do any harm by walking on them, but be guided by the pain - once you can walk without acute pain, then start building up your training again - and ease off if it returns.
I know how painful the little sods are, so I sympathise!
Best wishes,
Pip
