I have pain on my inner knee, likely a torn medial meniscus. It hurts the most while simply sleeping on that side of my knee while my other knee lays on top of it. The injury occurred 8 months ago when the knee was hyperextended in a baseball game, and reinsured 3 months ago in a cross fit session while squatting, I was hoping it would heal, but it is nagging, and I am wondering if I should wait it out, get an MRI or just go straight to the arthroscopic exploratory surgery and trimming if needed. I can run on it, jump on it and still do most activities...just throbs at night and in certain inwards (medial) knee turns. What is the best approach towards helping it heal?
