my husband has been having pain in the area of where his tumor was last yr. he had 1 ft of colon removed with the tumor (which was contained). Some lympnodes were affected and did 6 mths of chemo. Scan's last month came back clean. He had an ultrasound, because they thought perhaps it was his gall bladder. that came back fine. he had a CT scan and they said they didn't see any tumors or masses anywhere, but did see a small area in the fatty section near where the tumor was, which was cloudy. They treated him for infection but the antibiotic cause the pain to go from his right side under his rib to the left side, from the bottom of his belly button up to center of chest. Once he stopped the meds he started feeling better. Wasn't distended, was able to pass gas, and pain is just back to his right side. The doctor said it could be fatty tissue being tightened, he used another terminology, and can't remember. Please help answer my question. Thank you
