question: I am a 62 year old water aerobic instructor and a retired PE Teacher.  Recently while teaching class chemicals were placed into the pool which caused chemical burns on my lungs.  This happened on Dec 2nd.  I have been out of the pool since then  My work scheduled consist of eleven 1 hours classes per week.  Is there any kind or respiratory therapy I can discuss with my lung specialist on Monday.  I still have shortness of breath and cold air is a trigger.
