<s>[INST] I am 66 yrs old, female, have been fit all my life...exercise regularly, do yoga and walk a lot. In the last year I ve had 2 bouts of pneumonia, 2 bouts of bronchitis and 2 just bad colds. This is about 1-2 months since the last cold ended and I m finding weird things with my chest, a tightness and light-headed, not really dizziness after just climbing some stairs or doing something quickly . I can still do my. Treadmill and step workout. Am I maybe getting asthma? I have a bit of a cough and ventolin left over from the previous episodes does help. [/INST] Cellophane You for contacting Chat Doctor. As per W.H.O, asthma is defined as "attacks all age groups but often starts in childhood. It is a disease characterized by recurrent attacks of breathlessness and wheezing, which vary in severity and frequency from person to person. In an individual, they may occur from hour to hour and day to day."IN your case first thing that need to be checked is wheeze. It can be checked properly by a doctor through auscultating your chest. Apart from that as you are taking Ventolin, it causes dilatation of your respiratory tract and hence relieves your symptoms. I would recommend you to start: `Tab Malika (montelukast) 1 tab daily for one month. It will subside the allergic component and help in preventing the symptoms. `Spy HY Chat Doctor.  </s>
