Suggest Treatment For Abdominal And Back Pain After Mirena Placement

Hi, I had a baby 3 months and 2 weeks ago. They kept me on petosin because my body was not pushing the blood out properly? I got a Mirena inserted a while back but I am having wide spread abdominal pain with back pain and I have brown discharge every other week sometimes every week then after brown discharge I bleed a lot then it goes away. The abdominal pains are sharp and usually very sudden. I know when I was around 7 weeks pregnant my papsmear came back abnormal and led me to believe I had cervical cancer but ai transferred OBGYNs and the new one said they shouldn t have done the pap while I was pregnant at all.
