For some reason my Knees and legs hurt when I'm on my cycle. It's out of control. The pain is unbearable and I feel like I'm going to pass out! What is going on? I can't take this anymore. It makes it to where I don't want to move when I'm on my cycle. My stomach hurts as well, but it doesn't compare to the pain nd acheness in my legs. Is anyone having the same problem? I keep forgetting to mention this to my doctor.
