My husband had a mild stroke last September, he saw his Dr. last week wants to start walking 40 to 45 minutes a day, he has put on some weight, well we don t go even 15 minutes when his chest starts burning and his left arm feels like there s no circulation. He is taking HBP meds and for cholesterol, is this something we should be concerned about, he won t go back to his Dr. he says he doesn t like him
