Hi there. I have had right side abdominal pain on and off (mostly constant) for the last 6 weeks or so. Sometimes the pain radiates the lower right, but it s mostly in the upper middle or upper right and wraps around my back. I have had lab work come back normal. I have had a catscan and the wall of my gallbladder is 4mm. They also found a cyst on my liver that has grown since my last catscan in 2007. Then upon an ultrasound the cyst seemed to have also grown a small bit more. About one inch in total I believe. The ultrasound didn t show any gallbladder stones. I had an endoscopy and colonoscopy where 2 polyps were removed and sent to pathology, all non cancerous. they did biopsies of my stomach and I don t have Crohns disease, ulcers, or colitis. But the pain is so bad it sometimes wakes me up at night. Tomorrow I see a oncologist about the cyst of my liver. Being that he is an oncologist makes me very nervous. Is it possible for a simple cyst on my liver to turn into something more serious? Thanks in advance for any feedback you can give me.

Hi. Thanks for your query and an elucidated history. Read and understood it. The simple cyst when said to be simple means it is not thought to be cancerous or so. Stop worrying if both the ultrasonography and CT scan had said this to be a simple cyst. Now about the pain in the abdomen. This is right sided - off an on - sometimes radiates to the lower right side and wraps around the back. With the normal CT scan and USG, this may be due to the following reasons:Colitis - inflammation on the large intestine on the right side. UTI -Urinary tract infection / IBS Irritable Bowel Syn Chat Doctor.  I would advise you the following:Get the urine, stool and blood checked. Take a course of an antibiotic and metronidazole, probiotic and an anti-spasmodic. If this does not solve you problems further tests will be necessary.
