Hi
My daughter went to Trinidad on vacation many years ago, on her return she started complaining of stomach problems.  She had cramps, diarrhea, vomiting.  I have taken her to several doctors, she had many tests but no one can tell her what is wrong with her.  The problem started when she was in junior high school, she is now in college there are no changes.  She takes over the counter medication which does not help most of the time.  Can she be suffering from a stomach parasite, and if so, can you help her?  Thanks
