The last point heralds much importance because most of the times, complications borne out of illnesses are caused not due to the nature of the diseases alone, but mainly due to one's own negligence in understanding the seriousness of the condition and hence letting it build until the discomforts becomes too much for the patient to bear. In other words, the biggest mistake is to take things to the anvil before seeking medical assistance. Remember, medicine is a specialized domain, and ordinary mortals, with their common sense or fractured knowledge, cannot gauge a medical condition in its real dimension. Only a medical specialist could perform a diagnosis convincingly, and it is to such a person that one needs to rush to than making one's own conclusions and self treating in a worse case scenario.
After all, here, one's life is at stake. Not any silly thing to experiment or play with!
