I think I have an umbilical hernia. I had it when I was pregnant and it's stayed, along with my pregnancy weight gain. I'm going to try and see my gp but I was wondering what others' experience of this had been like? It doesn't hurt and it disappears when I lie down. I'm trying not to panic (I have health anxiety) but I would like to better understand it. Is there anything I can do to reduce it? Would losing weight help?
