PLEASE HELP, I have a herniated ambilical?

i am 4 weeks postpardum and ive had a herniated umbilical since late pregnancy. i can feel the hernia under my belly on and it didnt bother me before but now its starting to hurt a bit, i used to feed my daughter and she would kind of sit on my belly but now i cant feed her that way because it hurts to put pressure on it. should i be worried. i thought it might go away on its own but it dosent seem to be getting any better
