My friend had radiation on monday, her hubby said afterward she was in excrusiating pain and exausted and suffering.. but the next day she went to work at her cleaning buisness.. and then got home and was in pain again.. does radiation hurt right away? she claims she had a low dose radiation. Is this possible? I thought they would mak her head or something but I saw her the next day and no marks or nothing.. she looked normal.. I think she is faking it..
