Overuse injury

Dance for multiple hours 3x a week, run or walk daily as well. My right Achilles is giving me a ton of shit right now, definitely an overuse related thing, tried hot baths, slow walks, hasn’t healed, stretching doesn’t work feels like I’m back at day one and it’s bee 5 or 6 days. What do you guys usually do? How often does this happen and how do I avoid it? What are remedies?
