Breathing and head weight problem. I have been suffering from throat infection for the last couple of weeks. I took azikem 250 mg tab for one week. After one week, I felt like incomplete breathing. Breathing became slow. I went outside and walked around, but nothing changed. Also I feel like sinusitis (head weight) especially while I get cold, I feel something going upto the head. I live in Jamshedpur, India for the last one year. I started smoking before 1 and half year. Is smoking cause for them or weather etc. How to cure it. Kindly help me out with proper guidance. Thanks
