Please pray for my dad!

My dad got polio when he was 4yrs old (a yr before the vaccine came out) and the doctors told him he would never walk again, he was in and out of the hospitals. He was determined to walk and he did and hasnt stopped since, he is very strong and very stubborn. Over the past few years he has had 2 heart attacks and 2 major back surgeries. He has been diagnosed with post polio syndrom. This is something that is not currently treatable. He is very weak and tired and his legs are starting to give out. Its so sad for me to watch. He is seeing a new doc now that is very interested in his case and sees how determined my dad is to not let this over come him like he didnt when he was a kid. I am just praying this docotr will be able to find something to do for him!!! They have tried so many things and nothing has helped. I hope he will be able to walk me down the aisle....pleasse pray for a miracle!!!!!
