As someone who has suffered an Achilles Tendon rupture, I cannot stress enough how important it is to make 100% sure this does not happen. Think about 6 weeks of total immobilisation + 3 months of hard recovery even with a very good physio + about 2-3 years of fairly frequent pain + in most cases some kind of lifelong aftermath.
Do. Not. Treat. This. Lightly.
