Ive put an application in to join the infantry (regular) and have been training for selection which i am about to recieve a letter for. But I sprained my ankle whilst playing footy a while back now. The problem is, i really need to train for selection but everytime i run hard I get a nagging pain on my achillies just above my heel. The pain doesn't come until after ive finished. It's been about 12 weeks now since i first sprained my ankle im starting to worry about this injury ecoming chronic. I just cant afford to rest on the run up to selection. Is there any advice anyone can offer on the matter?
