Hi D.!
I have had several Ovarian cysts. My first one (in 2001) ended up disolving on it's own, but my OB/GYN changed my birth control pills, and I didn't have one for several years. I've recently had several, and now that I am a nursing momma, they switched me to a different birth control pill that is safe for me to take while nursing. My doctor told me that the cysts feed off the hormomes, and they tend to follow the menstraul cycles, so this is why the birth control pills help - regulate the hormones so the cyst don't form.
I had heard of several different things that could be done naturally, but I can't do any of them until I'm done nursing. I had been talking with Peggy, the owner of the Healthfood store called "Abundant Life" in Lewisville.
My internal medicine doctor said that if my pain didn't clear up, then I might have intestinal issues, and some things did show up in my CT scan (which also showed my cyst.) But again, I can't really take much meds or do any natural treatments (cleanses, supplements, etc.) until I stop nursing.
So I haven't really persued much yet, as I plan to stop nursing when my daughter turns one next month. Then I was going to do an intestinal/abdominal/female organ cleanse from the Abundant Life store, as I've had several friends go talk to Peggy there, and Peggy really helped them out and they feel a lot better now.
I don't know if you are comfortable with the natural route, but if you aren't on insurance, then I would recommend contacting her.
