Hello! Some back ground- I have had 2 knee surgeries on my left knee. One in January 2011, with a torn medial meniscus (minor tear) and an ACL tear. Then a second surgery in September of 2011, with a torn medial meniscus that had to be surgically repaired. This past Friday, I was throwing the football with my friends and when I jumped up to catch the ball I landed funny. I felt a pretty big pop and had a lot of pain on the side of my knee where my meniscus was repaired. My knee immediately started swelling, couldn t bend my knee at all, and I couldn t walk (this was probably the worst pain out of all three incidents as I have been able to walk after the previous 2). This went on for the rest of the weekend, and I was in so much pain that I couldn t sleep. I took Advil and kept my knee on an ice machine. However, finally last night I was able to sleep and I woke up with very minimal knee pain and swelling. Originally I though I tore my meniscus again. However, with the pain and selling decreasing so rapidly, I was wondering if left over scar tissue from the previous injuries could have caused this much pain.
