Thanks for your comments and suggestions. I had thought maybe it was detergent but then thought that I would have the rash all over my body? Anyway, I decided that it is worth looking into so I went and bought some laundry soap for super sensitive skin today.... bras are in the wash right now.... and I won't use any fabric softener... I"ll let you know if it helps - thank you :)
Sounds like one of the Urticaria Family (Hives) I wonder if its something you are drinking or eating,are you wearing a new Bra of a differant material? check out the detergent you wash it in also any shower Gels or Bathing products, do you use any of the products for nursing Moms the creams etc?Think about it ,as it does seem as if it is related to the Nursing , but dont stop the Nursing better you suffer for a short while than deprive Baby of the best thing that ever happened to them!!
