CHATHAM-KENT, Ont. -- To escape "hell," Pam Lozon is willing to face the risk. Plagued by multiple sclerosis - now unable to play with her son or enjoy the touch of his hair on her skin - Lozon believes her "last hope" is a controversial and unproven procedure. With the help of her family, the Chatham woman is trying to raise $15,000 for a trip to California for the treatment that is unavailable in Canada and banned in many U.S. hospitals. She prays it will slow or reverse the disease's ravages and give her four-year-old son Joey back the mom he deserves. "I can't do anything a normal mom can do, like run or stuff like that," said Lozon, 27, who has so far raised $1,800. "I'm always so tired. There's no energy at all. Playing with him outside without falling. Swimming. Button his shirts. Tie up his shoes. Touching his hair, I can't feel that. I haven't felt that since 2009."
