8.00pm. Aikido class. Semenyih Dojo.
As I was sitting down in seiza on the hard floor to start the class I felt a sharp pain at the back of the left knee. From the back of the left knee the pain radiated upwards to the caft and tight till it disappeared at the buttocks region. Trying to distribute the weight equally between the two legs didn't bring any relief. Finally transferring most of my body weight to the right leg gave some relief. I wondered if the student noticed that I was sitting not upright but slighting tilting towards the right.
The first time I experienced some pain in the left knee was one week ago during the Aikido seminar in Melaka. As the pain was not bothering me I dismissed it as sore muscles due to sitting in zeiza for too long. Then the next morning I felt the pain shooting up the left tight and the leg becoming a bit stiff. The Hulu Langat traditional Chinese medicine massage therapist whom I consulted said it was muscle sprain and after more than one hour of massage I experienced tremendous relief, as if some weight had been removed from the tired leg. The therapist said that I would have to return for more massage treatments in order to heal the injury completely.
In retrospect I am not sure how the pain came about. I don't recall ever hitting my knee cap on the floor due to a bad fall. Maybe as I am getting on in years, the muscle-skeletal and the nervous system are starting to degenerate as well. Well, I will have to find another way of sitting in seiza until the left knee recovers.
