You told you had asthma. Was it diagnosed by a physician and what are the medications you are taking? You also did not mention about your age. There is a different entity called as exercise induced asthma
which starts 10-20 minutes after completing exercise and persists 30-45 minutes. It is more common in dry, cold
weathers and while running. On all other occasional, patient do not has any other symptoms. If your symptoms were consistent with this, then you should take metered dose inhaler Asthalin
2 puffs before starting exercise atleast 15 minutes ago. But if you have asthma also apart from the time you are exercising, then you should use formoterol-budesonide
MDI 2puffs twice daily BD through spacer along with montelukast-levocetrizine for two weeks followed by levocetrizine once daily. For your current problem, please take MDI asthalin 4 times daily. Go to a pulmonologist and consult. Hope, I satisfied your queries.
