Hi Doctor, I am 29 years old. My right leg is affected with polio and is about two inches shorter than the left leg. When the polio struck me at 2 i could not even manage to sit, but gradually over the years after some operations and exercise i can walk with a limp and sometimes supporting my leg with hand. over the years there has been a gradual decrease in my my stamina and i get breathless just after climbing 3-4 steps or covering 50 metres on the ground. The leg it seems require increasing support. The foot drops, and sometimes bends inward when it becomes too stressful to walk. I have been cycling for 4-5 years to get myself around which i find more convenient even for the shortest distance. If it adversely affecting my leg strength? Also i get breathless and start panting easily while walking, do i need to be worried? I am 5feet 1inch tall and weigh 62kgs.
