Hello and hope you are doing well.
With a past history which is positive for eczema
, the most likely cause for the rash could be eczema
again. People who suffer from this disorder should avoid contact with triggering factors like soaps, cosmetics, jewelry, clothing, and detergents. Sometimes sweat, changes in temperature and psychological stress are known to trigger these episodes. So, the best way to prevent attacks is to identify those substances which you are allergic to and avoid them.
