Today at my visit with Sherlene (the massage therapist) we (I) diagnosed all my possible causes for the left side trauma. They included insufficient calcium supply, running with laces tied a hole too low, preliminary arthritis, overcompensative running for another problem, etc. Then I traced all my left side aches backwards in time and now remember that the first place to hurt was my left ankle which, this morning, had horrible flexibility after yesterday's run. It stiffens up a lot and was the root cause of me dropping a hole on the shoe laces, which probably led to the foot aches and the hip pain. My hip was not tight today while the ankle was a wreck. So I am writing the alphabet in cursive with my left foot as I type and it is amazing how often in cracks as I keep it loose. Meanwhile I'm raiding the vitamin drawer for calcium since I never drink milk or other providers of the bone and muscle builder.
