Blocked ducts

My goodness... I've a blocked duct. There's white blister at my nipple, and super painful hard lump on the right side of my left breast. Hurts like hell when I hold baby and he pressed against me. Hurts like crazy when I feed him on this breast but I know I must bear with it and keep feeding him on this breast in order to clear the blocked duct. Some people recommend using a needle to poke the blister but I won't want to do that! Sounds pretty scary... I may get my hubby to do that for me. Gosh...
