I have a weird nerve issue, also. I had a lateral release done when they did my Patellofemoral, and I’ve had major discomfort on the lower lateral area near my knee. The second I put pants on it feels like something big and hard swells up in the knee, like a golf ball, or sometimes a baseball, in there. It’s not a sharp pain, but it’s so uncomfortable and just the amount of bend you do when you walk really irritates it. I’m so glad the weather is warm again and I can wear shorts for the next several months. I’ve mentioned it to both my second opinions and they don’t know what it is and don’t recommend much so I’m just living with it.
