If sitting cross-legged or getting up from the floor feels painful or uncomfortable, it could be more than just stiffness — your knees might be signaling an underlying issue. Knee pain can be caused by early signs of arthritis, weak muscles, past injuries, excess weight, or poor flexibility. To ease the strain, try gentle stretches, strengthen the muscles around your knee, and avoid sitting on the floor for long periods. Use proper posture and support when you do. Also, maintaining a healthy weight can significantly reduce pressure on your knee joints. Consult a doctor if the pain is persistent, if your knees feel stiff or swollen, or if the discomfort affects your daily routine, like climbing stairs or sitting comfortably. Clicking, locking, or a “giving way” sensation in the joint are also warning signs.
