Thanks for your question on Health Care Magic. I can understand your situation and problem. You are having momentarily wheezing with tightness in chest. This is characteristic feature of temporary bronchospasm. This is seen commonly with allergic exposure and emotional disturbance like (crying, laughing etc). This can also be seen in stress, anxiety. So better to avoid dust, pollens etc. Avoid sudden emotional behavior like laughing, crying. If you are having stress, tension and anxiety then avoid them, be relax and calm. Don t worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
