question: I am 60years young, builder of 40yrs. My first pain started at my coxac about 9 months ago after doing sit ups on a decline bench. I find it hard to sit for long periods 1 or 2 hours . I have server pain behind my left knee & serve pain down the left side of my left leg. When I massage down my leg I can feel small lumps down my leg. Over the last 4yrs quite a lot of varicose veins have appeared. Please help. Frank
