So, when I was younger (baby-early childhood) my legs were shaped like < >. They were really bad - they said they would need to break both my legs to repair the condition, but my mom refused and asked that we see how they grew.
Well, they straightened out pretty well, but I've always had random shooting pains around my knees, especially at night - they get to the point where I can't sleep sometimes, but since it's been happening for so long I've grown accustomed to it, I suppose. It usually only bothers me in the winter, as when it snows it's virtually impossible for me to keep my balance on ice.
I joined a gym in January, and have been going regularly. I generally try to do at least 20 mins of cardio and then go to the circuit room and go around the circuit 3 times. The cardio, however, has been a problem for me for about the past month because after about 10 minutes my knees hurt so bad that it's everything I can do to keep going for the next 10 without wanting to just fall over in pain.
Being as summer is coming, I want to shed this extra winter weight and know I'll need cardio to do so. The elliptical is what I generally use for cardio - any recommendations to make it a little less painful or a different cardio program to try?
