She also has had chest pain, pain in her stomach pain. She also has pain that has traveled from her left side , sometimes right side, sometimes her back, . Is it something really serious?

### output:

Hi, I am sorry to know about your daughters condition. I need to know a little more about your daughter before I can guide you properly. How old is your daughter? What is her kidney function like (serum creatinine level)? Has a urine infection been ruled out (by checking urine microscopy)? Small kidney cysts are common after the age of 40 years. If they are simple, (meaning clear contents, no solid mass or septa within the cyst), they can be observed with regular ultrasonogram. If they have any internal contents, then a Contrast enhanced computed tomography (CT) of abdomen is necessary to further characterize these cysts. If your daughters kidney cysts are simple, her urine microscopy and kidney function are normal, the need not worry much about the cysts. If she is young, then she needs to be evaluated for one of the inheritable causes of kidney cysts. Reduced kidney function can cause vomiting and weakness. This needs the attention of a Nephrologist. If her kidney function is normal, she needs to be evaluated by a Gastroenterologist. I hope I have answered your query. Please feel free to get back to me if you need any further clarification or assistance. Wish your daughter a speedy recovery, Warm regards,
