WHAT ARE THE SYMPTOMS OF OVARIAN CYSTS?

I have been having the following symptoms for 6 or 7 months: Pain in my lower right pelvic area into my lower back. The pain feels localized in one specific area--near my hip bone. The only time it changes is if I stand or walk 30 minutes or more. Then the pain sometimes radiates throughout my hip area and down my right leg. It also worsens sometimes if I lay on my right side. I am 46 years old. I have been having erratic periods for about 2 years now. At this time, I haven't had a period for approximately 10 weeks. A couple of days ago I began having a brown discharge with a small amount of blood. This lasted for approximately 24 hours then stopped. After that, I had no pain in my side for a day or 2. Now the pain is back worse than ever. About 6 weeks after I first began having these symptoms I went to my gynecologist for my yearly PAP. She also does an intravaginal ultrasound to check the ovaries. But when I got my letter from her office, she said the results were normal. This was about 5 months ago, and the pain has just gotten worse. It is not unbearable, but I also do not have a job outside the home. If I did, I don't think I could deal with it. By the way, my mother had to have a complete hysterectomy when she was 37 years old because of uterine and ovarian cysts. But she bled so profusely that the doctor had no choice but to remove her uterus. And both ovaries had huge cysts on them. But there was no cancer. Could you please help me find some answers?
