Frustrating, humiliating, and hurtful — how awful it is to have a doctor not believe you. Sometimes symptoms and issues are unknown, and sometimes doctors have a hard time either understanding or "seeing" what is wrong. Different illnesses and diseases can be tricky. Some are all over the place with symptoms, some individual to each patient, and sometimes medical tests cannot show what a patient is suffering. Differential diagnosis, misdiagnosis, and even not receiving a diagnosis can be major problems for patients suffering through issues that are hard to explain to those who don't understand or dismiss their concerns. I recently had a doctor's appointment for rib pain, swelling, and movement where the ribs shouldn't be moving. But I couldn't show the doctor my pains, because I couldn't make my ribs move and hurt on command. I didn't agree with the doctor's assessment, which was that perhaps I was born this way, because I haven't always had the swelling, movement, or pain. I only began having these problems in the last year. I was told to get a second opinion, and I left the appointment in tears.
