Thought I had a groin muscle pull from the dance class I was taking. I was very active & fit and ate a good diet. I had a colonoscopy @ 55 & was told I was good for 10 years. I am now 61. The pain didn't go away so I went to my dr. who sent me to a gynecologist and still it was thought to be a musculo-skeletal problem. I went to chiropractic & acupuncture & still no relief. Then my stomach started hurting intensely so I ended up w/3 visits to the ER & finally a CT scan & another colonoscopy found a cecum tumor & metastasis to the liver. An endoscopy showed no problem inside my stomach by the liver was swollen & pushing in to my stomach causing the pain. Eventually the liver shrank back & I have not had any more stomach problems.
