Hernia??

[Skywalker]

Hi ladies... just noticed a spot on my tummy that's harder and sticks out more than the rest of my tummy, and it occasionally has sharp pains in that spot when I move. It doesn't hurt to touch or push on (which I've tried lightly) I am about 3.5 weeks post-partum and I was doing a ton of physical cleaning, lifting, carrying today... I know I shouldn't have, but I need to move out of this apartment at the end of the month. I'm afraid I might have given myself a hernia. Has anyone else had experience with this? What do you do if you have a hernia? Is it something I should try to be seen for immediately or does it correct itself with rest? Thanks!
