I am an obese man of 51 years of age. I want to start walking again to lose the weight I have put back on. My problem is the bad right knee. When I use a cane in left hand for more than, say, 7 minutes, my left wrist and elbow are painful as they were both broken in my high school years. My question is: Will a walking/hiking stick in the left hand aid the bad knee nearly as well as a cane? Right hand is out of the question as I slipped on ice this winter and now that is broken. Thanks for looking.
