Yellow stool & Yellow Specs...

Hello,

For the past 8-12 weeks I've been seeing yellow stool.  Ive been feeling pretty fatigue'd generally bloated and been having headaches come and go.

Ive been to teh doc three times and they are convinced its a reflux issue and they put me on prilosec.  im not convinced.  Theyve done ct scan, ultrasound and xray and found no blockage or anything.  however they found i had a fatty liver and an enlarged spleen.  Previous to all of this, i just got over strep throat which I was on anti-biotics for (i didnt finish the last 5 days of amoxicillin)


Since doing a little reasearch Im wondering if its Strep virus went internal on me, or maybe the antibiotics caused what I read.  Which is that I could possibly be suffering from a Intestinal yeast infection.  So I changed my diet and started eating yogurt once a day.  

I've since noticed my stool going from yellow/clay colored to just this morning to a dark greenish brown with yellow specks....

Does that mean its going away?

Whats your opinion as to what im dealing with?
