Horse shoe symptoms and conditions

My son was born March 2007, when he was 8wks old, to much of my surprise I found out that I was pregnant again. Mirena sounded perfect!!!! I had it placed 7 weeks after my 2nd son was born in Jan 2008. I had what I still assume is normal with any type of birth control method, irregular bleeding,cramping,some slight mood swings. That all seems normal to me when you mess with you body like that. Aug 1, 2008 I woke up at4am with awful abdominal pain sooo bad that I turned to my husband and said that I think I have to go to the hospital. I decided that if I could fall back asleep then its probably nothing major. I fell back asleep (or passed out, I don't know) The next morning I was hurting so bad I couldn't lift anything, couldn't stand up straight, felt weak and felt as though I had rocks in my stomach but had an empty feeling at the same time. The pain was all over my abdomen, stabbing, shooting,pinching. I also had pain aroung my belly button and a noticeable discomfort about my pevic bone. Finally I called my husband to come home, went to the hospital, they took blood, cultures, did an exam and did a ctscan. All normal! WHAT!! Aug 11th still having pain and now having MAJOR HOT FLASHES. I find myself getting so hot and irritated that I cant be around the babies because I am afraid I will yell at them. If I get in a little disagreement with my husband it will most likely end with me saying I want a divorce (I noticed another lady with that same problem) Today I had a ultra sound done and it came back what my (new) doctor says is normal. The problem with that is that one of my ovaries is split and is NOW shaped like a horse-shoe. I was pregnant for almost 2yrs straight and had lots of ultrasounds NOT ONE TIME did anyone say anything about a odd ovary. I'm just going to make a educated guess that it wasn't deformed till after the Mirena. Now I am wanting to remove it but feel like I should get every test known to man first to rule out any other possibility. I really don't want to remove it. I am afraid of getting it removed and even more of getting pregnant when I already have two 10 months apart and still in diapers.
My biggest question is wanting to know if hot flashes are related or if I might be having something else going on. Am I the only one with he hot flashes? I have them all day long!!!!!!!!
Also I noticed after reading other post that some other things may be related like, piercing headaches, itchy flaky oily scalp, weight gain, ear drainage, lower back pain, oily skin, increased smoking, in-grown hairs in inner thigh area, joint pain, fatigue, decrease sex drive.
