65 female just informed to go for ct scan for gallstones? I think. I don't know much about this part of the body. Can someone enlighten me? I should appreciate it. I have a healed crushed right foot and ankle, after 4 surgeries. and a really long stay in the hospital. I have lupus,allergies, 3 back surgeries, right ear surgery , and front brain small tumor surgery, diabetes, and of coarse both "arthurs" , and oh, don't let me forget depression by all means, oh herpes II, please forgive me if I've left out anything. Yes, I've had colon polyps which were positive, but cleared.
