In the (power)lifting scene, I have really enjoyed the articles by Austin Baraki et al. from Barbell Medicine on pains and aches in the context of physical activities. See for example https://startingstrength.com/article/aches-and-pains or https://www.barbellmedicine.com/blog/the-barbell-medicine-gu...

In a nutshell, the idea that there's a straightforward causal link between something being physically broken in your body and you feeling pain is simply wrong. Sometimes people feel pain in various body parts without any detectable physical changes and sometimes classical training injuries, like herniated spinal disks, can be found by medical imaging without the person feeling any pain at all. Also the common advice to rest until the pain subsides is often - but no always - wrong; there are plenty of anecdotes of people with completely fucked up knees or ankles or back starting heavy powerlifting program and suddenly healing from their injuries or at least learning to use their body in such a way that the injuries don't bother them anymore.
