Hi i was just browsing for infomation on hernia's i have got the exact same symptoms as you.Mine started about 2 years ago with a little lump appearing next to my hip bone which felt uncomfortable when lying down at night,it popped up then went again. After visiting my doctor several times she said it was my intestine digesting food and because i was thin i was feeling it but ive always been thin so why am i getting it now???She did an examintation and said she couldnt feel anything and nothing was there when i coughed so said it was nothing to worry about. I get a bit of pain with it but like i said its mostly at night im worried because i want another baby soon and scared this may make things worse.I have a 2 and a half year old daughter and sure it all started when i gave birth to her.Have you been advised that its ok to fall pregnant with this problem then???? The only way to describe the lump is its like a sausage shape and im fine if i lie on my side.
