Lower left quadrant lump and pain?
When looking at a woman's pelvis from the front, I know that both the left ovary and sigmoid colon is located in the lower left quadrant. My question is, is the left ovary located in the front, with the sigmoid colon running behind it, or is the left ovary and sigmoid colon side by side or is the left ovary located behind the sigmoid colon?
The reason for this is because I can feel a lump in my lower left side, right where I think my left ovary is located, however, know that the sigmoid colon is located in this same area and so I'm trying to determine whether the lump is caused by my ovary or by my colon? I had an ultrasound done a few weeks back and it didn't show an ovarian cyst (I am prone to getting them often and also have endometriosis). I'm not constipated and have bowel movements (although painful), so it can't be constipation causing a lump in my colon...?
Anyways, any help would be muchly appreciated, I have searched everywhere on google for a picture and for help to try to figure out my above questions about the location of the left ovary and sigmoid colon with no luck.
