Hives

ive been itchy with hives on neck n arms,scratching like an ape.im so careful with my food so it could be the hand sanitizer i use which is eucalyptus n organic so shouldnt have allergy. could be cheap hand wash chemicals.i need to drink detox juice as im full of toxins n drink kefir n prebiotics again.i rub neem leaves on hive to relieve itchiness.
