I have been misdiagnosed so many times for health issues, I feel like doctors need to specialize within domains and they are only allowed to practice within that domain. So much advice given out by general practitioners is useless and only treats symptoms of health conditions. It literally took me 4 years to figure out a health issue as a bounced from doctor to doctor as they all scratched their head. Some doctors even made incorrect diagnoses which lead to treatment which was actively harmful to my condition, it would have been better to not see those doctors at all since they set back my recovery by months. We dont let electrical engineers build bridges so why do we give doctors so much freedom in their practice?
