Wheezing sound?

Dear Doc,
Occassionlly, when I breath out, There would be a coarse rattling or low pitch (wheezing?) sound.  After clearing my throat or coughing hard, there will be phelgm discharged and the sounds would sometimes go away.  Sometimes not.  There are no other symptoms. I would like to know if this is suspision of asthmatism or is this likely to lead to it. Any preventive measures?  I saw a GP who prescribed Salbuterol (100mcg Albuterol (Salbutamol) and Beclomethasone dipropionate BP 100mcg. Pls let me know if it is alright to use them.  Also, is there any clinical methods of screening/x-ray to determine if I'm asthmatic?  Tkx

It is very difficult to know from what you described whether you do or do not have asthma. There is a fairly easy way to make the diagnosis of asthma. It is to have a pulmonary function test, which measures the air that flows through your lungs. The medications that you were given are to treat asthma. They are safe, but will not work if you do not have asthma.
Good luck.
