Q: Does a clicking or popping knee mean something is wrong? A: In most cases, no — as long as it isn't paired with pain, swelling, or inflammation, it's considered normal and harmless. If those signs appear together with the clicking, it's time for an exam.
Q: What causes the knee to click when standing up or sitting down? A: Most of the time it's the kneecap not gliding smoothly in its groove, or a mild injury to the cartilage surface. It doesn't automatically mean osteoarthritis.
Q: If the knee hurts, is it still okay to walk? A: It depends on the case. With osteoarthritis, staying completely still lets the thigh muscle weaken over time, which can make the knee more painful and unstable. Good walking means flat ground, cushioned shoes, short comfortable distances, and listening to the body — stairs, slopes, and squatting are best avoided.
Q: If the knee clicks but doesn't hurt, does it need an exam? A: Not urgently. There are three signs to watch: pain, swelling of the knee, and the knee giving way. If any one of these appears, it's time to see a doctor.
Q: Should I take calcium for joint pain? A: Joint pain has nothing to do with taking calcium. A lack of calcium is what causes bone loss. Joint pain comes from worn cartilage, from fluid building up in the joint, from inflammation, or from inflammation of the capsule and the fluid around the joint. Bone loss is the thing that needs calcium replacement — and usually bone loss does not cause pain until you break something. Taking calcium carelessly can also cause stones to form.
Q: Why do my joints hurt when the weather turns cold? A: Cold weather does not damage the knee joint. When it turns cold the muscles tighten, the blood vessels tighten, and the fluid in the joint gets thicker, so the joint feels slightly stiff and becomes more sensitive to pain. People who hurt when the weather turns cold already had something going on inside the joint to begin with.
Q: What does joint pain at night mean? A: Pain at night is a sign worth paying more attention to. Inflammatory conditions and gout are the ones that hurt a lot at night. Osteoarthritis is the opposite: it hurts when you move around a lot, and it eases off when you rest. If the joint pain is severe and comes with fever and with losing weight, go and get examined right away.
Q: My big toe is swollen and too painful to walk on — what is that? A: That is the classic picture of an acute gout attack: swelling, heat, redness and pain, coming on suddenly with no injury involved. A joint infection can look exactly the same, though. So if there is no way in for bacteria and there is no fever, we lean towards gout — and you should still go and get examined right away.
