Working clean wheelchair for son (Warren Woods 12 Hoover)

The hospital sent my son home with a walker instead of a wheelchair. It is not working out well, he is basically walking on footballs due to extreme swelling on his feet and legs to the point where socks won't even fit him. I hate to see him in so much pain. So if anyone has one that they are no longer using that would be so awesome. Thanks 1,000 times in advance.
