I have intermittent wheezing which is usually coupled with coughing that brings up mucus. it happens at anytime, gym, morning,evening & lasts +-30mins?

Wheeze, cough: If these symptoms followed a recent head cold they probably signify an asthmatic bronchitis which can be a prolonged illness requiring antibiotics, broncodilating and anti-inflammatory inhalers and oral steroids. If these symptoms have been going on for a prolonged period, they may be asthmatic without associated infection. An evaluation by a physician for diagnosis and treatment is warranted

Need to be Evaluated: You need to be evaluated as it sounds that you likely have mild to moderate intermittent Asthma. However, you need to be evaluated for other causes as well.

Lots of possibilitie: Asthma is a chronic inflammatory condition of the lungs. Typical symptoms include cough, wheezing, shortness of breath to name a few. Cough can have multiple causes including asthma, post nasal drip and reflux disease to name the most common. But other more very serious disease can cause cough as well like infection or cancer.
