Oo normal yan especially pag engorged or may inflammation, pero if sobrang sakit or may pus/redness, better makonsulta ka ng doctor or LC para masiguro it's not mastitis na talaga. A few of us sa mommy group namin went through the same thing, ang dami naming inisip na serious pero naging okay lang after warm compress and proper latching, pero may iba talaga na kailangan ng medical help kaya better safe than sorry. How long na yang nangyayari sa iyo?
