I am 47 old woman, obese, and have had umbilical hernia since my last pregnancy 14 years ago. It was alright, but lately, it became problematic and since yesterday, the area has been very painful, tender and now I have severe pain specially when I move which is around my navel and and under it. When I lie down, my abdomen is flat, no umbilical (hole). I am worried what is wrong with it. There is nothing protruding from it though.
You are going to have to immediately go the ER. The gut is being pinched in the hernia, and it can cause a catastrophe.
