The short explanation
Knee pain in your 30s is common and usually not a sign of early wear and tear. One frequent cause in women is pain around or behind the kneecap, sometimes called patellofemoral pain, which is typically worse on stairs, squatting, sitting cross-legged on the floor and getting up after sitting for long. It is often linked to weak thigh and hip muscles, a sudden increase in activity, weight gain or the way the kneecap moves. Many people improve with targeted strengthening exercises and changes in daily habits, often guided by a physiotherapist.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Other causes depend on the details: a past twisting injury, swelling, locking or the knee giving way suggest a problem inside the joint; pain in many joints with morning stiffness raises questions about inflammatory arthritis.
- Indian homes involve a lot of floor sitting, squatting and stairs. Small changes such as using a low stool, avoiding deep squats for a while and building up activity gradually can ease the load on the knees.
- Body weight affects knees too, since every step puts several times your body weight across them.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot find the cause of your knee pain. That needs an examination, and sometimes an X-ray or other tests.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is this pain coming from the kneecap or from inside the joint?
- Which exercises would help, and should I see a physiotherapist?
- Do I need any scan or blood test?
- What activities should I reduce for now?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Get help the same day
- Get care the same day if your knee becomes hot, red and swollen, especially with fever, or you cannot bear weight.
Book an appointment soon
- See a doctor within a few days if the knee locks, gives way or swells after an injury.
Raise it at a routine appointment
- Book a routine appointment with a physician, orthopaedic doctor or physiotherapist if the pain lasts more than a few weeks or limits daily life.
