I think that I was getting headaches ever since I was in grade 4th and it was from the year 1987 onwards. Sometimes my headache will be accompanied by vomiting and little that I knew that it was the tell-tale signs of an impending kidney disease.
My kidney disease was caused by my own immune system attacking my body. But I am not sure that tonsillitis was the cause of it. My mother in those days will just tell me to gargle vinegar with salt if I have a sore throat. Sore throats should never be set aside or ignored as it will cause your body to invade itself. So the result is a kidney disease which will lead to failure if not a heart valve condition.
I remember when my teacher asked the class to monitor their pulses, it was in our math class. One of my classmates counted 90 while mine was 119 and that is in a sitted relaxed position. In that instance I am feeling that something was wrong already.

So with a kidney disease it causes the blood pressure to raise up and sometimes the pressure is high enough that it causes headaches. I thought that having headaches was just ordinary in my case but it was not because it had been the symptom of my condition already before.
But now since I am not anemic the symptoms of anemia like headaches had been gone already and I am never more been thankful because of that, one misery of my life that I had won over, thanks be to God.
