Why would my Dieffenbachia Plants cause me to have such a horrible almost unbearable rash on my hands up to the elbows? While cleaning out the seemed to be dying leaves and stems, can't tell if it's stinging or itching?
Amy help will be appreciated~

the sap can cause irritation

Yes...and whatever you do keep your hands away from your mouth next time you get in contact with the sap. Can cause the tongue to swell and cut off air ways...hense the name "Dumb Cane".
