Hence it is important that one takes care of the health of his/her basic, external, and internal senses, to remain 'sensible' in life. Whether it is eye, skin, or taste, if there is any inkling of an ill health, or if the external sense notifies you that everything is not so right, don't waste any time to consult a doctor. It is always better to fix medical issues at the earliest, or conversely, it is not advisable to wait until the last minute to start taking treatments. This point heralds lots of importance for 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. Heard the saying 'nipping in the bud'?
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, it is our own body and senses, and not a thing to experiment with?
