How are you feeling?
When any patient complains of “knee pain,” the initial differential diagnosis in most of the cases includes: Osteoarthritis, Ligament damage, Meniscus damage or Patello-femoral disorder.
I think you have some meniscus injury as per your symptoms.
Where is your pain exactly? When did your pain begin, what were you doing at the time, and what were the initial symptoms?
Do you experience any grinding, locking, catching, or giving way of the knee?
Are there any positions that make your knee more or less comfortable?
What is the quality of your pain (sharp, shooting, dull, etc.)?
Have you tried anything to help the pain and, if yes, has that been successful?
Have you ever had surgery on your knee? Do you have any hip or ankle pain (both hip and ankle pain can refer pain to the knee, and vice versa)?
Keep me informed.
