A month back I was diagnosed with acute bronchitis after suffering from severe cough. I took some medicines and cough withered away within 15 -20 days. Thereafter i went to trekking to Himalayas for 10 days which was really very cold. After coming back from there for the last 2-3 days I can see blood while I blow my nose and today I saw blood while coughing as well. I used to smoke befor being diagnosed with acute bronchitis but have now smoked barely 2-3 ciggerates in 35 days. Though I am seeing an ENT specialist today itself should I be worried because I am tensed as hell.
