A normal X-ray is reassuring because it rules out bone fractures and severe arthritis. However, X-rays cannot show soft tissues like ligaments, tendons, or cartilage, which are common sources of knee pain. For temporary relief, you can take over-the-counter pain relievers like Ibuprofen (to reduce inflammation) or Acetaminophen. I also highly recommend resting the joint, applying ice, and using a compression sleeve. Because pain with a normal X-ray often points to a soft-tissue strain or muscle imbalance, please consult your doctor for a physical exam. They may recommend physical therapy or an MRI to look closer at the soft tissues.
