You may have fractured your ankle and so I would encourage you to have an Xray. If it is not fractured then the soft tissue injury
that you have sustained should improve with time, rest, elevation, ice, anti-inflammatory medication and splint
age. You may need crutches to help you walk in the short-term and physiotherapy
for crutch use instruction and rehabilitation
. You could certainly flare up the symptoms from your OCD lesions in your talus.
