X-ray of lumbar

This afternoon I went to Ng Teng Fong for followup of my L4L5 fixation surgery.  The surgeon looked at the x-ray and do not see much progress in the bone growth.  However, he is happy to let me go jogging.  It is quite difficult as there are still discomfit when I run.  Plus my knees are going me problems as well.  So I will stick to cycling and swimming.
