For About A Month I Have Been Experiencing On/off Again

for about a month i have been experiencing on/off again itching, bumps and welts on my entire body. sometimes they are everywhere and other times it is localized. i have not added anything new to my diet, and i have not began using any new sin care or personal care products.

today i am officially 2 months postpartum and this constant itching and burning/pinching feeling is preventing me from breastfeeding my daughter.

please help.
