This case looks like one injury, but it isn’t. A sharp pull during sprinting and a deep ache at the sitting bone may both be called “hamstring pain” — but they behave very differently.

In this episode of The Foot Detective, we separate acute hamstring strain from proximal hamstring tendinopathy, unpack why stretching can make both worse, and explore how to manage load, rebuild strength, and return to running without repeating the same mistake.

Because not every hamstring needs length. Some need better loading.

If you want to unlock the problem, the knee is key.
