51 year old male, on blood pressure and antianxiety meds. 300 lbs, not diabetic. Changing eating habits. Left knee badly injured in his 20 s. Experiencing sharp stabbing pain and numbness in Right outside thigh. Left leg buckles unexpectedly. Back, hips, neck was adjusted by a chiropractor, no relief. Thinking Left knee needs replaced, compensating by putting full weight on Right leg. X-rays negative... MRI scheduled for the end of the month. Anything else come to mind? :)
