First, I would like to mention at this point and time that doctors are also human beings. They can't do magic in a day or two to make a diagnosis if the patient suffers from any acute/chronic illness. Suppose it is just flu, cold, fever, or any viral infection as the author mentioned. In that case, doctors need to check the vitals/parameters required initially and wait not prescribing unnecessary medicines if the patient's condition is not serious. They could not make any crucial diagnosis or go for any diagnostic tests all of a sudden.
Our human anatomy is a scientific wonder and remains mysterious though we are much advanced in medical sciences with technology innovations and longevity of lives globally. We know about our earth and the galaxy around us. How many of us have known about a new structure found (not an organ) namely interstitium, fluid-filled sacs all over our human body?
Mr. Ramachandran Pattabiraman rightly stated that we must believe the doctors and his treatment would cure the illness. We must have our family physicians near our home or somewhere else whom we believe. The family physicians are aware of their patients' history and physical/allergies to any drug and treat them accordingly. Secondly, we should not search for any drug for an ailment on the computer or self-medication. Every individual has his/her unique physical system and treatment differs even though diagnosed with the same illness. Nowadays, patients themselves diagnose and request doctors to treat them with injections/antibiotics during the initial visit. Patients would like to get cured instantly. If it is a viral cold/fever/gastroenteritis, it would take at least five-seven days to get cured. If the patient requires any specialty services care his case will be forwarded to the concerned specialist doctor. We cannot blame all doctors as business-minded, a few may be the case.
