Lou Ferrigno is offering a warning after he said he was hospitalized following a bad reaction to a pneumonia vaccine. “My whole arm got filled with fluid. It looked like something out of a horror film,” the "Incredible Hulk” actor told Inside Edition. The 67-year-old former bodybuilder said he went to a Rite Aid to get the shot. Ferrigno said he went to the ER, where they gave him a CAT scan and antibiotics through an IV, keeping him overnight.
