Cameron Redpath, 18, disabilities officer for Lancashire, who has cerebral palsy and uses a powered wheelchair, said: “I was coming back from the Co-Op on Quernmore Road at around 9pm in my powered wheelchair when my curb bar got stuck on a raised flag and because of the force it launched me out of my chair and onto the floor.
“I was in an initial state of shock at first but then when I came round, I realized I could not move my right leg due to severe pain, almost like a dead leg.
“I usually can get up off the floor quite easily, but I knew this was not just a tumble.
“Luckily, two cars stopped at the side of the road to assist me in getting up off the floor and making sure that I was okay.
“The gentleman ran back to his van to get some alcohol antiseptic gel so I could rub on my hands and knee where there were cuts visible, my knee being more significant as blood was running down my leg.
“I managed to get back in my wheelchair and drive back home but because of the initial shock I did not manage to get his name and I really would like to thank him for his amazing help.
“Once I got home my Mum managed to help clean me up with initial bruising round my knee starting to show which doesn’t help my Cerebral Palsy as it can make me seize up which it did do that night, so I had to manage my pain with a hot water bottle and over the counter medication.
“I woke up very stiff the next day from the impact of the fall but luckily have not had to go to the doctors or a walk-in centre as I am managing the pain at home.
“My knee is still swollen but the grazes are healing now and it’s business as usual.
“I’m so grateful to the man who helped me, I would have had to ring home or for an ambulance to help get me back in my wheelchair.
“I filled in a questionnaire for Lancashire County Council and they are looking into the matter.
“Fingers crossed they do something about it. I just want to warn people that this area is really bad.
“This could have been a lot worse for me which luckily it wasn’t, but I am in a lot of pain and will be more than likely for a few days.
“I’m very disappointed that Lancashire County Council have not looked after this area but I’m just so grateful I came out of it not too bad.”
Cameron currently works at a building society in Preston and travels there every day on the train.
Cameron’s accident happened on July 16.
