Hi Everyone,
Thanks for your replies. I went to see my MD yesterday and she said the lump on my ribs is just a cyst and not to worry about it. It should probably go away on it's own.
As for the flank pain and abdominal pain, she thinks it may all be due to endometriosis (I have horrible periods and ongoing pelvic pain for a year now) and sent me to an obgyn who I also was able to see yesterday as an urgent consult. He seemed very good and has me scheduled for a diagnostic laparoscopy on March 12.
This may sound like a dumb question but does anyone know if he will be looking at the entire abdominal area or just at the pelvic region? I was a little overwhelmed by seeing him so quickly yesterday that I didn't think to ask him. Is it possible for growths to be on my kidneys or gallbladder? And I wonder if this cyst has anything to do with that. I know I should've asked him all this yesterday.

All he did say was that my kidney could be enlarged from endometriosis on the urterer.
