I Had A CT-Scan That Showed That My Cecum And

I had a CT-Scan that showed that my cecum and bladder are fused together. I have had pelvic pain for the last two years, but it intensified and I asked my primary care doctor for a CT Scan. I was then referred to a oncologist who wanted another CT Scan and set up an appointment with me to see a urologist to look at my bladder from the inside, and a gastraologist to do an upper and lower GI/colonoscopy. The tests came out fine stating that I did not have cancer, but there was a budge noticed in the upper left section of my bladder and there appeared to be irritation at the base of the cecum. The oncologist had stated that the second CT Scan showed that my bladder and cecum were not attached. (?) The oncologist then referred me back to the ob/gyn who perform a total (robotic) hysterectomy on me in August of 2012. The ob/gyn doctor examined me and referred me to a neurologist because she said my symptoms are similar to a pinched nerve. She then stated that if that did not work she would refer me to a Pelvic Pain Management Physician. I have seen the neurologist, had a MRI done, and the results are that I have cysts on my spine and three cysts on my left kidney. I have received a prescription for the pain I have been having, and was scheduled to see the neurologist in six weeks. I think that the pain in my lower back, legs, buttock and thighs are from a sciatic nerve, but the pain I feel in my pelvic are and lower abdomen has to be from something else. When the pain is at it's worse, it feels as if something is in my rectum and vaginal canal. The pain is constant, and can be intense. It hurts to lie down, to get up, to walk or just to stand. It seems as if I have two different types of pain. Please, tell me what should I do. I am so tired of going from one doctor to another from April 2014 until now. I had a heart attack in October 2014. Please, tell me what should I do? Do I change doctors and get second opinions?
