After sitting motionless or avoiding squats for too long, bending your knees might cause creaking or catching pain. This could indicate patellofemoral pain syndrome, where the kneecap struggles to track properly. It's typically not serious if temporary, but it signals a sedentary lifestyle and weak muscles around the knee. A few sessions with a physiotherapist can strengthen your quadriceps effectively.
Descending stairs is normal—it loads your knees with 2 to 7 times your body weight. Persistent tingling often stems from overuse, like repeated jogging impacts or fitness jumps irritating the cartilage. Rest for at least a week, then ease back in with low-impact activities like brisk walking or swimming. Consult a doctor if pain lingers.
Unprepared for intense sessions—like 2 hours of Zumba, step aerobics, or a week of skiing—your knees can overwork, swell, and ache. Rest, apply ice wrapped in a cloth, and elevate the leg. If no improvement in 24 hours, see a doctor for pain relief, an X-ray, or ultrasound to diagnose the issue.
