Ankle Sprains (Persistent Pain)
Ankle sprains (ligament injuries) are extremely common. Most heal after six weeks with a combination of rest, ice, elevation and physiotherapy. In a proportion, however, there are ongoing problems such as persistent pain, swelling, instability or an inability to return to sport. This is not normal and may be due to several causes such as an osteochondral lesion within the ankle, an occult fracture, tendon injury, failed healing of the ligaments or neuropathic pain. An MRI scan is often required to establish the nature of the problem.
Treatment of the problem depends upon the underlying cause but options include further physiotherapy, activity modification, the use of an ankle brace or surgery to repair the damaged structures.
