I always answer people' knees questions on here as I lately had my 13th surgery within March so I am a seasoned knee injury veteran. And I will recount you what I tell everyone else. See an orthopedic (bone and joint) doctor. He/she will discuss your symptoms beside you and take xrays and an mri scan. The xrays will probably show zilch, but the mri will give you your answers. The knees is a very complicated integrated with 4 most important ligaments and tons of cartilage including the meniscus. People on general-health-care.com will give you their best guess and speak "I had like peas in a pod thing!" but you will never know in need getting images of your knees taken. I am very learned on the subject, but I wouldn't begin to report to you what is going on without looking at imagery of your knee. So please, see a doctor and catch it checked out.the earlier the better.you do not want to be similar to me and have 13 surgeries and huge scar...trust me. Good luck to you.
