Hi,
so sorry to hear your story. You must be in agony.
As ankle sprains have a tendency to self-heal reasonably quickly, the first treatment (ice/ elevation/ compression/ pain management/ gradual loading) is as per guideline.
We expect a healing time of about 3 weeks for mild sprains without any further intervention. This can sometimes take a little longer (moderate sprains), as the simple first exams like Ultrasound only give an estimated evaluation of the severity.
If this does not happen, the injury is likely considered 'severe' and further investigations need to occur. Recovery of severe ankle sprains can easily take 3+ months.
Not sure whether your GP was consulted at that stage, but commonly, you are sent straight away for an MRI or to a physio/ osteo/ chiro/ podiatr. Please rest assured that your bones must have already been in the right place. Had they 'popped out', you would not have been able to put any weight an that ankle.
It was worth a trial but obviously, the next 8 weeks of Chiro did not further your healing, nor did the 6 weeks of physio.
You then had a second US - what was the result in comparison to the first one?
Your current management plan is to undergo an MRI and I presume, you will then be sent to a Specialist Orthopaedic Surgeon for a consultation.
There is no point in discussing who was wrong or who was right or whether you were in the correct injury management plan from the start. There are still many variables in ankle sprain healing and we cannot predict all of them. Important in your case is that many avenues were explored, that we now know that your sprain appears to be more severe than initially expected, and that you have been referred for further investigations.
I recommend for you to wait for the MRI results and the Orthopaedic consult. They will explain what is going on and re-define your management plan.
In the meantime, you could also discuss with your physio whether they believe an ankle splint (referral to Podiatry?) might help with your pain, esp. when you walk long distances.
While remote case discussions are always difficult, it would be interesting for all here to follow your case. if you could let us know how your recovery progresses, this would be greatly appreciated.
All the best,
Awhina
