Why is it important? Let us explain with an example (based on a real life story) -
One fine day, for no good reason, a young man starts itching in his right foot.
He decides not to pay attention to his itch and carries on with his hectic work life.
A couple of days later, the itch returns to both his feet.
The man isย worried that the itching is now more intense just because he didn't addressย it sooner.
Immediately, he visits the medical doctor. After waiting for 45 min, he finally explains the intense itching to the doctor.
The doctor recommends some basic itch relief medicines and sends his blood for lab testing.
The lab reports strongly indicate that the person has a rare heart disease, only possible for one in a million person. There is no cure for the disease.
The patient's life is completely devastated. He recalls eating all junk food, never having sufficient sleep and enjoying parties all weekends with wine and dancing.
With the heavy heart, he quits his work and immediately returns to his home city and shares the news with his family.
His parents took him to the local doctor the very next day.
The new doctor listened to the story, examined the legs and asked the young man one question - "did you change your socks recently?"
The confused man replied "Yes". He picked up a new pair of socks when he last left for his new work city.
This new doctor prescribed the same medicines as the previous one, with one addition - he requested the patient to start wearing only cotton socks.
Within a week, all the itching disappeared!
The young man happily paid a visit to the new doctor, thanking him with all his hearts. He then requested the doctor to explain what went wrong.
The experienced doctor explained that the nylon socks that he was wearing previously minimized his sweat evaporation, which thereby caused minor skin irritation and itching. Luckily, cotton clothes help evaporate the sweat easily which helped cure the irritation.
Summary: The healthcare system is a collection of humans who can make mistakes. Yes, doctors, nurses and lab pathologists are humans too! Further, even the healthcare system is typically heavily overloaded, especially during crisis periods such as COVID-19. On top of that, even the computerized and automated lab tests are rarely 100% accurate - just because human body is really that complex. Therefore, it is important that the patients really learn what is happening to their body and more importantly, why. Panic never helps. Instead having an understand of how our own body works does help a lot. When a patient provides these necessary information to the doctor, then the treatment is simple, fast and effective. Only seldom a doctor will be experienced enough to ask you the right question!
