two hour for radioactive tracer to show in small intestine.

So I recently had a HIDA scan done. After 60 minutes into the scan, the nurse comes over to me and says that the radioactive tracer has not showed up in my small intestine, and I\'ll be re-imaged every 5-10 minutes until it does. Fast forward 45 minutes later and still no sign of the tracers in my small intestine, the nurse tells me she will wait 15 minutes and try one last time before sending me away. FINALLY, at the two hour mark the tracer shows up in my small intestine. All systems go and on to the CCK. I thought for sure that something would come of this.
However, today I get a call from my regular doctor and she says the report is normal. I am at my wit\'s end dealing with pain, nausea, etc. I have had 3 abdominal ultrasounds, a CT scan, blood work done twice, and now a HIDA all with normal results. I am going bonkers!!! Please, if you have any suggestions or similar experiences I am BEGGING for your input - anything will help. Thanks!
