type three sphincter of oddi

I had my gallbladder removed the summer of 2006 and a month  later started having nausea and pain just under my ribs on the right side.  After months of tests with the local doctor and no findings I started seeing a gastroenterologist in a larger city.  He found that I am not digesting fat well.  He thinks the nausea and pain is being caused by the sphincter of oddi and I am to meet with him the end of this month to talk about what to do.  

I am a 50 yr old female.  I have been sick everyday for almost a year and a half.  I wake in the morning sick to my stomach.  Most days it goes away after drinking a couple of glasses of diet coke.  On days that it doesn't go away I take phenergan.  I don't eat until noon becuase that way I stay well enough to get some things done.  Anywhere from an hour to three hours after I eat I start getting nauseaous again.  by evening the phenergan doesn't help it much so I take a med to help me sleep and go to bed.  I wake in the night sick to my stomach.  It goes away with either a couple of diet cokes or phenergan.  

If I eat very little fat the nausea isn't as bad and the pain and diarrhea isn't as bad.  My bed is elevated  becuase over the last year I have developed reflux and I am on prilosec and zantac.  Every time after I eat I have mucous that comes up my throat and I have to spit it out.  It only happens after I eat and when I first get up.  I don't have a cough.

Every part of my body has been tested and I am fine except this nausea, diarrhea, and pain in my right side.  The doctor says the diarrhea is from not digesting fat.  

Do my symptoms sound like sphincter of oddi?

The doctor said it may be type three.  Is there any help for this type three?

Is this damaging my liver?

Any help you can give me would be appreciated.  I don't even know what to ask the doctor when I see him.
Thank you.

You might want to glance through this to get an overview of all three types of SOD: http://www.emedmag.com/html/pre/gic/consults/031505.asp

What you're describing does sound a lot like SOD. But your doc can't possibly say which type you have unless you've had an ERCP with manometry and I'm assuming that hasn't been done at this point.

You might want to ask the doc if he can prescribe some smooth muscle relaxor meds to try and see if they might be of some help. There are a couple of different types ranging from 'standard' relaxants to some 'heavy duty' forms that have a greater number of side-effects. But if either form works, it might give the doc an indication that you are experiencing spasms.

I know you've said you've had a lot of testing done, but have you had an MRCP done? What about liver enzyme levels and amylase levels? Are they elevated?
