Hi there, I think misdiagnosis definitely can happen. So many things overlay each other, mimic something else, or are comorbid. If you aren't thinking you got the right diagnosis, try again. My son has been seen now probably by 20 different health care professionals. He's had a major mental health crisis starting last winter and he's been in two different hospital settings, had several eyes on him and assessments. I feel confident that we've got right diagnoses now. But honestly, a lot of things are treated with the same medications. If you gave more details, I'd love to talk through it with you. Do mistake happen? Yes, sure.
I think you need to provide a lot more details. Some diseases are easier to diagnose than others; some are very hard to diagnose and take a lot of time and expertise that most docs don't take the time to acquire. Some are difficult because they are diagnosed by symptoms without any diagnostic tests being ale to definitely determine the existence of a particular disease. Medicine isn't a field with a lot of knowledge. It is a field with a lot of information and a lot of study being done but the human body is very hard to understand at this point in our history. We spend a lot more time and money throughout history building weapons than we do figuring out health. Tell us what disease you are concerned about and why you think your diagnosis was wrong. Also, you say you were diagnosed by a student, which also demands explanation. Usually a student is supervised by a physician and it's the physician who makes the diagnosis, so that is something you also need to supply more info if you want any answers. Peace.
