When your knee hurts under pressure, it might mean that there’s inflammation, fluid buildup (effusion), or issues with how the kneecap is aligned.
If you feel pain when pressing on your knee, it could be a sign of a few different things. One possibility is that there is extra fluid in your knee, known as knee effusion. This extra fluid can make the joint swollen and very sensitive when touched. If it is swollen, you should see a doctor immediately. Another possibility is that the kneecap (patella) is not positioned correctly, a condition sometimes called patellar malalignment. When the kneecap is out of place, it can cause the tissues around the joint to become irritated, leading to pain with pressure. Studies have shown that people with knee pain may have lower pain thresholds, which means their knee can hurt more easily when pressed. Additionally, conditions like patellofemoral pain syndrome (often called runner’s knee) can also make your knee sensitive to touch. Remember, while this information helps explain what might be happening, it’s important to talk with a healthcare provider for a proper checkup if your knee pain continues or worsens.
