hello I got polio in 1942 as a 3-1/2 year old girl. I am now 79 and have cancer (multiple myeloma). My legs are getting weaker and unsteady. The polio is in my left foot (much smaller than the right one) and lower left leg (muscle was affected). I was actually very strong all my life and used the left leg very well. Now, I am very tired all the time. My left leg is at least 1/2 inch or more shorter than the right, keep my gait off all the time. I have tried lefts many times, but then my back seems to hurt. I always exercised, but because I now have had 3 compression fractures in my back (that have healed), I don t know which ones to do. I always rode my 24 speed outside bike until this year, but am afraid now of a fall. I have a recumbant bike and try to use it. But I am honestly so tired lately. I needsomeone to confirm the PPS and guide me through the proper exercise program. Thank you. Kaye Jones
