The short explanation
Pain at the front of the knee after starting running is common, and you usually do not need to stop completely. It is often caused by increasing distance or pace too quickly, weak hip and thigh muscles, or running technique, which together put extra stress on the area around the kneecap. Many runners improve by reducing their running for a while to a level that does not worsen the pain, building up more gradually, strengthening the thigh and hip muscles, and checking footwear. Low-impact activities such as cycling or swimming can help you stay fit while the knee settles.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Pain on stairs, squatting and after sitting for long is typical of kneecap-related pain. Pain on the outside of the knee, swelling, locking or the knee giving way may suggest a different problem.
- Running on hard surfaces, downhill running and sudden increases in training are common triggers.
- A physiotherapist or sports medicine doctor can assess your technique and design a strengthening plan.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot confirm the cause of your knee pain. That needs an examination.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is my pain coming from the kneecap area?
- How should I adjust my running?
- Which strengthening exercises would help?
- Do I need any scan?
