The situation maintains at least six months.
I am used to cough when walking or talking.
Actually,I didn't worry about that before.
I thought I am still young and have enough resistance.
My friend's mom cough at times too,and she went to hospital taking X-ray examination.Unfortunately,the doctor regared that she mignt has lung cancer!
We were shocked when hearing the sorrow news.
Because of this case,I became worried about my lung!
I went to hospital for X-ray examination last week.Before the doctor told me that I am okay,I murmured that I don't wanna die!There are so many beautiful things I hadn't experienced!

God bless me,I have neither pneumonia nor tuberculosis!My lung in X-ray film is clean and healthy!

The doctor told me that allergy is the reason I cough.
