Hi. I was reaching for a remote while laying in bed. I heard a pop in my knee and felt something on the side /back of my knee. I m walking fine and only find pain with different tasks, like kicking some steps down the stairs but not all of the time. I just did this last night. I am a little frightened because I ve had many surgeries and one big one on my other knee. I don t see any swelling and just think I tweaked it a little but nothing serious. I m asking because I ve had major injuries that required surgeries and I didn t even know it. Any time I start to feel pain or discomfort, I now get a little panicked. Thanks for any advice/help that you are able to provide.
