Knee pain is very common and usually not a cause for panic. Common causes include minor injuries like strains or sprains, overuse, or gradual wear and tear, such as osteoarthritis. For temporary relief, you can use over-the-counter paracetamol for mild pain. If there is swelling, an anti-inflammatory medication like ibuprofen can be helpful, provided you have no stomach or kidney issues. Applying a topical diclofenac gel directly to the knee is also a safe and effective option. Along with medication, remember the R.I.C.E. method: Rest, Ice, Compression, and Elevation. Please consult a doctor if the pain is severe or persists.

For left leg pain after an X-ray, you should consult an orthopedic specialist (orthopedist) for an accurate diagnosis, and a musculoskeletal physiotherapist for targeted rehabilitation. To manage pain during physiotherapy, mild over-the-counter pain relievers like acetaminophen (paracetamol) or anti-inflammatory drugs like ibuprofen or naproxen can be helpful. Topical pain-relief gels containing diclofenac are also safe options to apply locally. Please consult your doctor or pharmacist first to ensure these generic medications are safe for you and do not conflict with any existing health conditions.

I understand you have been dealing with knee pain. For temporary relief, you can try over-the-counter pain relievers. Acetaminophen is helpful for pain, while oral NSAIDs like ibuprofen or naproxen can reduce both pain and inflammation, provided you have no contraindications like stomach or kidney issues. A topical NSAID gel, such as diclofenac, is also a very safe and effective option applied directly to the knee. Alongside medication, resting the joint, applying ice packs for 15 minutes a few times a day, and keeping it elevated can help. If the pain worsens, or if you experience severe swelling or cannot bear weight, please consult a doctor for a proper evaluation.

It is common for knee pain to return years after a PCL injury. This typically happens due to mild joint instability, muscle weakness, or early wear and tear (osteoarthritis) resulting from the original injury, rather than a new tear. For temporary relief, you can use over-the-counter pain relievers: acetaminophen for general pain, or oral NSAIDs like ibuprofen or naproxen to reduce inflammation. Topical diclofenac gel applied directly to the knee is also a great local option with fewer side effects. Please use these short-term, and consult a doctor or physical therapist to evaluate your knee stability and discuss strengthening exercises.
