Lower leg and ankle pain can cover a range of problems and many of them from acute to chronic conditions. Lower leg pain can cover the likes of shin splints, or compartment syndrome, achilles tendinopathy. Whilst with ankle pain, you have various ligament sprains and tears that can have effects elsewhere. Often long term conditions have their route cause hidden in a previous injury that happened many years previously.
It is for this reason that we always look at what has happened in the past. Even if it was quite some time ago. Ankle sprains often cause long term issues as a result of not being fully rehabbed as components of the rehab have been missed. Achilles problems are more often than not a result of training error in athletes. Managing either of these problems and others requires that we ensure that nothing is missed if we are to ensure a complete recovery.
