Yes, do make an appointment with a gastroenterologist. It could very well be your bowels that you are feeling.
I have chrons and I could feel mine but mostly when I was laying down.
It could be that you just have an infection in your bowels and need antibotics.
good luck.
Thanks for the reply. Yeah, I went to the ob/gyn, but he told me my ovaries/tubes are ok. i know, i might just be paranoid because i do have an ongoing infection. he told me it's not a hernia, because it's not sticking out. i also heard for hernia, it's unbearable pain, but mine is not... hmmmm... i don't know... so confused. but i will make a GI appointment soon to get this checked out.
It could be a hernia. I had a similiar lump in 2001 on my left side. Thought it was something wrong with my ovary and went to my ob/gyn and she diagnosed a hernia and sent me to a surgeon and sure enough it was a hernia. I had outpatient surgery to fix the problem and I have had no problems since. I would advise going to the doc an having them check it out.
