Do i have asthma? please help? I really dont know whats happening to me!!!?

I don't think it sounds like Asthma, asthmatics don't usually have a tickle at the back of their throats that make them cough. It sounds like you have an upper respiratory infection with the mucus. I would go back to your Dr. You could have Pneumonia or Bronchitis. The flu symptoms would fit right in with the Pneumonia.
