my son has chron's disease and never had surgery. he had one treatment of stem cell therapy in Mexico .I was shocked later to see how thin he has become. He says he will be going for more therapy as soon as he gains weight. I am afraid he is being scammed. how can I convince him to get help in U.S. and which hospital will accept a patient in severe condition with no insurance.I am willing to get it for him but am afraid we wont be able to find a company that will cover his pre-existing condition.Where is the best place to take him?
