I have been offered a new job, based on satisfactory references and completion of a medical questionnaire. I'm not worried about the references, they should be fine, but the medical bit concerns me. It's very in depth and they want to know what meds I'm on. I'm on an anti-depressants and beta blockers for tension headaches & anxiety, and I used to have panic attacks. I also have arthritis, which is totally under control now, and none of my medical conditions will affect me ability to do the job, but still I'm really worried - can they withdraw their job offer if they don't like my medical records?
