Can I still run if my popliteal fossa hurts when running?

Generally speaking, you should not continue running if you experience pain in the popliteal fossa. The specific reasons are as follows:

The popliteal fossa refers to the area at the back of the knee joint, and pain here may involve problems with muscles, ligaments, or other structures. Prolonged running may lead to lactic acid buildup, causing muscle fatigue and resulting in pain in the popliteal fossa. Additionally, sudden twisting or straining of the posterior leg muscles during running may also cause such pain. Furthermore, conditions such as popliteal cysts or tendonitis can also lead to discomfort in this area. Continuing to run while experiencing popliteal pain may increase pressure and stress on the region, worsening existing injuries or inflammation, potentially causing further damage and prolonging recovery time. Therefore, when experiencing popliteal pain during running, you should stop running immediately.

If you develop pain in the popliteal fossa, it is recommended to seek medical attention promptly to avoid delaying treatment.
