question: I have a rash that was initially diagnosed as poison oak but did not respond to Clobetasol cream nor a Prednisone taper.  It is itchy and some spots are scabbed, some are red, some are turning into brown spots after going from a red bump to a fluid filled vesicle. Rash occurred aprox 10 days after a car accident where the air bags deployed. I climbed out of a ditch so was probably exposed to a variety of flora.  I have also heard a rash can be an indicator of cancer. Is this true? A friend wondered whether the chemicals inside the air bags could have irritated my skin. I am perplexed!
