英語で「整形外科を受診する」
Good morning. I'm Dr. Kim, your orthopedic specialist today. What brings you in — is it a pain or mobility issue?
I've been having sharp pain in my left knee for about three weeks, especially when I go up or down stairs. It sometimes swells a bit too.
Stair pain combined with swelling is a good indicator — it helps narrow things down significantly. Did this start after a specific injury or activity, or did it come on gradually without a clear cause?
