As foot and ankle specialists, we can't ever say it is 'just a sprain' because even a sprain signifies some amount of damage to the foot or ankle. After an ankle sprain, there is a higher likelihood for recurrent ankle sprains. Prompt treatment reduces the occurrence of ligaments healing 'loose' and this is one way to prevent future ankle sprains. Completing either home therapy or physical therapy also helps reduce this. Furthermore, custom orthotics that help to correct foot position will aid in reducing recurrences by holding the foot in a more stable position.
