From childhood , I used to suffer breathing problem when there was a dust allergy , I can't sleep in that night , more over I can't breath properly , but this suffering will clear perfectly when morning came. I don't how this was occurring only at night time. As the time goes , now my age is 27 , Now I am suffering the same breath problem during day time also , In that time I can't walk and feeling very much pain in the back side ., hence I met with one pulmonologist , and taken PFT and concluded I have asthma ,he asked me to continue the Seroflo inhaler (250 mg) during morning and night one puff and some tablets. I was taking the medicine one month continuously , when I am taking the medicine , that time I was feeling very good ,if I not taking that medicine one day, I am again feeling some what breath taking problem ( not much) . I really want to know , why it was happening , Do I need to take those medicines continuously through out my end ? Please advise.
