My wife(age 42) is facing the breathing trouble from last night, breath exhale and inhale coming with sounds, she is unable to sleep and attend any of her daily chores. Though she is not on any medication, but last such situation happend to her only 10 years back, just to give a background her family has asthma history. Kindly advise a quick relief from severe difficulty and also suggest a regular prevention. Thank you, Mahipal
