... like a full blown cold, itching in the back of my throat and roof of my mouth. My eyes are red, itch and tearing. I have Difficulty swallowing and the inside of my nose is bright red and raw and stiff. My nose will not stop running and I cannot breathe through my nose. I'm hoping someone can tell me what to do for relief. Not sure if I should take an antihistamine or not. NEVER touching this stuff again!!!
