I am 27 years old, i have two kids and had an Umbilical Hernia Repair done 9weeks ago. I've had 2 infections since then and a CT scan done with inconclusive results if there is a new hernia or just scar tissue at the site. I've been cleared to pick up my 25lb daughter and was wondering what are signs that I've overworked or injured the site....i have what looks like a dark blood blister that hasn't swelled our popped up at the very bottom of the surgical incision that just showed up today. Thanks for any advice given. Megan
