Sorting out my back and neck pain with a bike fitting

I often have back and neck pain when cycling. That is why I am trying out a bike fitting. Roel Peerenboom, a cyclists who owns a bike shop in The Netherlands, invites me. He has a closer look at my bike settings, such as the position of my saddle and handlebars. There is always too much tension in my muscles, caused by fibromyalgia (a chronic illness with pain), but maybe by a wrong position as well? A well-fitting bicycle does support active motion by balancing you equally on three points of contact: hands, butt, and feet.
