Redness/Burning sensation on scrotum after indirect application of Tretinoin Cream 0.025% and reaction with soap.

I applied some Tretinoin to my inner thigh after noticing stretch marks. I no longer have scheduled appointments with him. Contact with genitals occurred, obviously, with no adverse effects until this afternoon when I took a shower and an apparent reaction occurred with the soap I was using. Only the scrotum was affected. Burning sensation and redness. I immediately washed the area for several minutes with cold water and applied Aquaphor to the area. Is this an emergency?
