Welcome to HealthcareMagic forum,
The most common condition in groins when it is sweaty is Fungal infection
called tinea cruris
.This needs an anti fungal treatment.Take oral tab AF(150mg) once a wk for 4 wks.You can continue using nizoral
cream at night as you were using earlier.Also start abzorb powder over the affected area in morning.I am sure you would be all right with this ,if not let us know ,so that we can guide you further.
take care ,
