My father had polio but he was lucky in that he could walk. He just had one leg thinner than the other. I'm sorry about your condition. Too bad physical therapy has not helped. Do you get any exercise? How about acupuncture or massage? Not sure if they would be available where you live though...

As for your flashback, if it is a sad memory I can understand why it would make you cry...on top of how depressing it is to be stuck at home...(((Hugs)))
