thanks for using health care magic. To air pocket called is an indication there was some trauma caused to the lung tissue, with escape of air into the space between the lungs and diaphragm. Nothing is being done because the physician s certainly the amount of air is not much enough for an invasive procedure to be done to remove the air. Conservative treatment of this condition, called pneumothorax
is usually opted for, depending o the clinical condition of the patient, the radiologic characteristics and the evolution of the patient, which is judged both clinically and paraclinically. You should not be surprised if routine X rays are done on you. IN case of any deterioration of your condition, adequate invasive procedures
to avoid crushing or collapse of a lung tissue through insertion of a test tube shall be done.
In case you notice worsening of your health status, pain becomes more and more severe or difficulties in breathing increase, notify your treating physician. If not, the situation usually improves with time and might take a week or two. So , I pray you stop worrying that much but stay vigilant to improve any negative changes to your doctor.
Thanks and hope this helps,
