Respected user, HiT hanks for using Chat Doctor.come have evaluated your query thoroughly.* There is no mention evaluation of x-ray chest, pulmonary function test which evaluate lungs.* If not done, strongly recommended and if done and normal then it proves to be a psychosomatic issue.* Recommended to - meditate thoroughly - deep breathing exercises - YOGA - avoid smoking (active / passive) - avoid exposure to dusty environments, if needed to use face mask.  - avoid stress, anxiety.  - have regular sound sleep of 8 hrs. Hope this clears your query. Welcome for any further guidance. Regards dear take care.
