3 stretches to relieve knee pain

Muscles that support the knee—primarily in the legs and hips—need a certain amount of elasticity to work properly. That “give” allows the joints to move through their range of motion easily. If the muscles are tight, they might cause chronic knee pain. Stretching leg muscles can improve flexibility and reduce knee discomfort. Experts recommend doing dynamic stretching before workouts and static stretching afterward. One should consult a doctor if pain persists after a few weeks.
