I've been working with a great PT the last five weeks. I was in so much pain a few weeks ago that I was thinking of selling my bike and just sinking into a seditary lifestyle. In a couple sessions we reduced/ellimated the pinching pain in my sacroiliac joint. And worked through a muscle knot in my lower back to gain some mobility. But the plot thickens.... As it turns out, I am the most inflexible human alive. At this moment I am extremely asymmetric, with my right hip(among many joints) not functioning like it should. Super limited rotation. The problem appears to be that my muscles and contective tissues and are shortened and stiff and just not moving, which led to this presenting as back pain, because of all the stiff tissue tugging and pulling my hips every time I take a step or pedal, thus my lower spine experiences an unfair work load. PT is confident we can get me back to normal, but it's going to take time and patience and pain. Super basic stretches are really hard for me even to get into right now. It's really embarrassing to be so completely dramatically out of wack. This isn't out of the blue, I've had my back seaze up least once every couple years since high school. I've got a little bit of scoliosis, and also a muscle tear on one of my left quads when I was 14 set me up with some asymetry that's always been in the back ground but never slowed me down much. Until now with this hip thing. It's by far some of the worst shap (mobility wise) I have been in. Listen to what Coach Dee is saying about the hips here. If I was doing these stretches 6 months ago I would never be in this position now. Think I may take a few weeks away than risk injuring myself.
