Knee pain after exercise can be a common concern, especially for those who engage in activities like running or stretching. Based on your description, it seems you experienced a sudden onset of pain in your left knee after an intense stretching session, particularly while performing a leg press. The pain appears to be more pronounced when standing up after sitting for a long time and when bending the knee. This pattern of pain can indeed suggest a few potential underlying issues, including inflammation, overuse injuries, or even mechanical problems related to the knee joint.

Firstly, it is essential to understand that inflammation of the knee joint, often referred to as "knee joint inflammation" or "knee synovitis," can occur due to various reasons. In your case, the sudden pain after stretching could indicate that you may have strained a muscle or ligament around the knee, or it could be a sign of inflammation in the joint itself. Inflammation can arise from overexertion, improper technique during exercise, or even pre-existing conditions like patellar tendinitis or bursitis.

The fact that the pain is more noticeable when you first stand up after sitting suggests that it could be related to stiffness in the joint or surrounding muscles. This is common in cases of tendinitis, where the tendons become inflamed and painful, especially after periods of inactivity. The pain subsiding after walking around indicates that movement helps to alleviate stiffness, which is a positive sign.

In terms of management, it is advisable to follow the RICE protocol: Rest, Ice, Compression, and Elevation. Resting the knee will allow any inflammation to subside. Applying ice can help reduce swelling and numb the pain. Compression with a bandage or knee sleeve can provide support and limit swelling, while elevating the knee can help reduce fluid accumulation.

If the pain persists beyond a few days or worsens, it would be prudent to consult a healthcare professional, such as an orthopedic specialist or a physical therapist. They can perform a thorough evaluation, which may include physical examinations and imaging studies like X-rays or MRIs, to rule out any serious injuries such as ligament tears or cartilage damage.

In the meantime, it might be beneficial to modify your exercise routine. Engaging in low-impact activities such as swimming or cycling can help maintain fitness without putting excessive strain on your knee. Additionally, focusing on strengthening the muscles around the knee, particularly the quadriceps and hamstrings, can provide better support for the joint and potentially prevent future injuries.

In conclusion, while your symptoms may suggest inflammation, it is essential to monitor your condition closely. If the pain does not improve with rest and conservative measures, seeking professional medical advice is crucial to ensure proper diagnosis and treatment. Remember, listening to your body and allowing adequate recovery time is vital for long-term joint health and overall well-being.
