I use miconazole it causes my skin to be red, is this is a sign of allergy to miconazole?how to differentiate between fungal and bacterial jock itch?

It is typically: not easy to tell between the two mentioned, as both can reach a point of severity that would make the rash/ skin reaction appear similar. Both can become pustular and/or weepy, though fungal infections are typically less inflammatory appearing than bacterial. It is best that you see a healthcare provider to diagnose and treat your properly. Thanks for trusting in HealthTap.
