Elevated sed rate symptoms and conditions

Hello
I don't know if it is Mirena or not. It was placed almost 3 years ago... and about a year ago... ovarian cysts were driving me crazy...so my doctor placed me on birth control pills to stop ovulation... I had never had ovarian cysts before... But now, i don't know what to think...my primary doc and i have been spending about a month on all of my symptoms... IBS, really bad back and right side abdomen pain, all over low abdomen pain, I went for an ultrasound and found that my portal vein in my liver is distended, I am constantly exhausted and have an elevated ced rate. My primary doc is sending me to a GI specialist, but i am also going to see my ob. Could this entire thing be the IUD. I have had it for almost three years before these awful symptoms came around.
