Certain types of Pollen cause havoc , my Eyes stream , my Nose runs , my Head aches and I generally feel rotten.
Certain Perfumed Washing Powders , Shampoo's , Shower Gels etc can cause me to come out in Hives I literally want to scratch down to my Bones.
Certain Pesticides also bring me out in the worst case of Hives
Thank God for Antihistamines
