Knee pain?


I often experience knee pain after walking for about 3 to 4 hours.
This has been happening since I was 12 years old, and it continues to occur intermittently.
Sometimes the pain comes on suddenly, and it feels like my knee is being pulled apart.
Other times, it happens after walking for too long, but the sensation is always the same—it feels like my knee is being stretched.
I initially thought it was due to growth, but after all these years, my height has remained at 158 cm.
I have researched and found that being overweight can contribute to knee pain, but I only weigh 47 kg.
I would like to ask the doctor what this condition might be.
I have considered seeing a doctor, but my mother says it’s not a serious issue and not necessary.
Is that true? Thank you.

Knee pain can have many causes, and it's difficult to determine the exact issue based solely on your description.
However, it could be due to misalignment of the patella or softening of the cartilage in the knee.
Therefore, it is advisable for you to see a physician for a detailed diagnosis to identify the possible causes.

More Info


Knee pain can be a complex issue, especially when it has been a recurring problem since a young age. Based on your description, it seems that you experience pain in your knee after walking for extended periods, and you have a sensation of tightness or pulling within the joint. This could be indicative of several underlying conditions, and it is essential to understand the potential causes and when to seek medical help.


Possible Causes of Knee Pain
1. Patellofemoral Pain Syndrome (PFPS): This condition is common among adolescents and young adults, especially those who are active in sports. It is characterized by pain around the kneecap (patella) and can be exacerbated by activities such as walking, running, or climbing stairs. The sensation of the knee feeling like it is being pulled apart could be related to the alignment of the patella during movement.

2. Chondromalacia Patella: This refers to the softening and breakdown of the cartilage on the underside of the kneecap. It can lead to pain and discomfort, particularly during activities that put stress on the knee joint.

3. Ligament or Meniscus Injury: Although you mentioned that the pain has been ongoing for years, it is still possible that there could be a minor injury to the ligaments or meniscus that has not been properly diagnosed. These injuries can cause pain, swelling, and a feeling of instability in the knee.

4. Osteoarthritis: While it is more common in older adults, early signs of osteoarthritis can begin in younger individuals, especially if there is a history of joint injuries. This condition involves the wear and tear of cartilage, leading to pain and stiffness.

5. Growth-Related Issues: Given that you mentioned your knee pain began around the time of growth spurts, it is possible that you experienced conditions like Osgood-Schlatter disease, which is common in adolescents and can cause pain below the knee joint during periods of growth.


When to Seek Medical Help
While your mother may believe that your condition is not severe, it is essential to listen to your body. If your knee pain is persistent, affects your daily activities, or worsens over time, it is advisable to seek medical attention. Here are some signs that indicate you should see a doctor:
- Persistent Pain: If the pain does not improve with rest or over-the-counter pain medications.

- Swelling: If you notice swelling in the knee joint that does not subside.

- Instability: If you feel like your knee is giving way or if you have difficulty bearing weight on it.

- Limited Range of Motion: If you find it hard to bend or straighten your knee fully.

- Pain During Rest: If you experience pain even when not engaging in physical activity.


Conclusion
In summary, your knee pain could stem from various causes, including patellofemoral pain syndrome, chondromalacia, or even growth-related issues. While it may not seem like a severe condition, persistent pain and discomfort are valid reasons to consult a healthcare professional. A thorough evaluation, including a physical examination and possibly imaging studies, can help determine the exact cause of your knee pain and guide you toward appropriate treatment options. Early intervention can prevent further complications and improve your quality of life, so it is worth discussing your symptoms with a doctor.
