Hmmmm. I broke my collar bone around 10 years ago and didn't get it checked out immediately. No x-ray taken, just sent away. Meanwhile ever since I've been lop-sided with that shoulder more rounded and it's always ached.
Two months before my last accident, it started playing up, so much so that I knew it needed looking at. Following my shoulder separation, I mentioned to the consultant about my collar bone and he asked what the x-ray showed. 'No x-ray taken' said I to which he raised his eyebrows. At the weekend I had an MRI scan on it.
The point I'm making is that unless injuries are completely investigated, together with any requisite physio, they will come back to haunt you in later life!
Do hope she makes a full recovery and can get back to her serious training.
