question: I am a 40 year old female approximately 106 pounds.  I went to the ER with suspected gallstones and during the ultrasound they found a 6mm echogenic area.  I don't have gallstones, but I am going to a GI doc to discuss what could have caused my pain.My concern is the cyst on my Kidney and my lymphocytes were at 14%.  Could they be related?  They did recommend a CT scan, which I will schedule next week.
