Im 21 yr male and suffering from Mild bronchitis .
I have been taking medications from last 5 years but there is no cure .

Doctors has prescribed me BAYURAB , TELEKAST-L , COMBIHALE 200mg .

but these medicence give me relief for just 1 or maximum 2 days . afterwards the mucus and breathlessness occurs with some nasal infection.  

this problem has completely ruined my life , please suggest for proper treatment .
