Need Advice on Potential Malpractice Suit

Okay, ladies. This one is something that I NEVER imagined having to discuss nor seak advice for. I will apologize first because there is alot of information that I feel must be shared for anyone to be able to give me proper advice.

I used to be a very healthy wife and mother of 3. Then in January 2005, everything changed. There were issues that arose that led to a diagnosis of fibromyalgia. I had already been diagnosed with polycystic ovarian disease, Hashimotos (an auto-immune thyroid disease), carpel tunnel syndrome on both wrists, and on-and-off depression. After my fibro diagnosis, any other issue that I had was automatically said to be due to the fibro. In November 2007, my family moved after my husband started a new job. Of course with the new location came new doctors. I found an amazing doctor who actually listened to me! That led to the discovery of my desmoid tumor (it is spelled correctly, but is a very rare item). After receiving horrid treatment from a major learning hospital/cancer center and also receiving devastating results from tests, my husband and I knew we had to move back home to have help as we fought this tumor.
In June 2008, we moved back to TN and in with my mother. I found a great team of doctors at Emory in Atlanta, GA. I will be the first to say that I was extremely blessed in finding this team. I had surgery (a 5+ hour surgery) to remove the desmoid tumor along with alot of soft tissue, muscle, and even a portion of bone. The surgery was a success!
Being back in TN, allowed me to go back to my gynecologist who had been treating me for almost 10 years before moving away. Of course, I wanted to go back to him as I had COMPLETE trust in him. During my July surgery, I had my right ovary "pop out" of my abdomen with a large softball sized cyst on it. They removed the cyst, only for my appt with my gyn 1 month later to show the cyst back at the same size. Due to not only that but a number of female issues, my gyn and I agreed it was time for a hysterectomy. I decided that I did not want a partial as I did not want to deal with cysts, and there are thoughts that the hormones are a risk factor with the desmoid tumors. My gyn would not operate until I had time to recover from the July surgery (an indicator that he was looking out for me, or so I thought).
So, in December 2008, I had a complete hysterectomy performed, or so I thought. My gyn came out and explained that normally this only takes 45 minutes but mine took over 2 hours because my right ovary had become entangled in the mesh patch that was used in my repair from the removal of my desmoid tumor. He said that he had worked hard to get all the pieces of that ovary out. His last words with regards to this were everything went well.
Fastforward to August 24, and imagine what a shock to find out that even though I had a complete hysterectomy, the surgeons were finding ovarian pieces and pieces of my falopian tube. During this period of time that I thought I had no woman parts, I was put on a medication that can cause severe pain if you still have your ovaries, and I was in pain and discomfort more days than not.
I do not like people who file frivalous lawsuits (like burning your mouth on hot coffee you have just purchased). And I do not want to be one of those people. But I am very upset that this doctor potentially at the least caused me more pain and discomfort than I would have had. His actions (or inactions) also required 2 more surgeries and all the bills associated with them.
What are your opinions on whether this is a worthy case? Also, who do you turn to (lawyers)? The other complication is that at the time of the last 3 surgeries, I lived in Canton, GA. However, the complete hysterectomy and the laparoscopy were performed in East Ridge, TN and Chattanooga, TN. What does that mean as to where I would have to file suit and what kind of accredidation (sp?) does a lawyer need to have? Thanks!
