Have you ever been told by a doctor that your symptoms are all in your head? When a doctor dismisses a patient's health concerns as nothing more than the product of their imagination, some call it medical gaslighting. Dr. Phil meets several women who claim doctors didn't take them seriously, which led to major health problems. Philecia was 29 when she says her life came crashing down after an undiagnosed lump turned into stage 4 breast cancer. Then, a woman says she saw 30 different doctors within five years for migraines before she finally got a diagnosis. And, how did a 27-year-old woman go from a competitive runner to using a wheelchair and needing open heart surgery? Dr. Phil gives life-saving tips on how to be taken seriously at the doctor's office.
