Terrible. As a fellow human being, I feel great sympathy for him. I have known pain from tendonitis in the ankles and from arthritis, but nothing in the realm of what he has suffered. I would not be pleasant to be around if I hurt as he described.
If he had a verifiable online fund toward getting treatment in America, I would consider giving, and I usually do not give to charity.
Joking aside, at this point I think he has much bigger problems.
