### input:
My 17 year old daughter has been suffering with recurring symptoms for almost 2 years now.  At first the "episodes" were occurring about every 4 to 6 weeks.  Now the "episodes" are coming weekly and last 2 to 3 days.  Here are her symptoms--extreme nausea and stomach pains, extreme fatigue, body aches and sometimes headaches.  Normally she does not have vomiting.  When the symptoms hit, she cannot function.  She cannot sleep at night and she stays in bed all day.  She is missing 2-3 days a week from school almost weekly.  Between "episodes" she is fine.  We have had an endoscopy of her stomach and ultra sound of her gall bladder---all was fine.  She has been tested for metal allergies (she had spinal fusion surgery at age 12 and has metal rods and screws in her back)--negative.  He CBC came back with her C reactive proteins high--over 12.  She has also been diagnosed with Polycystic Ovarian Syndrome.  We have seen 5 different doctors!  What could this be.

Consultations with 5 Doctors and some investigations, PCs, severe pain in abdomen making her miss school for 3 days every time, The symptoms being : extreme nausea and stomach pains, extreme fatigue, body aches and sometimes headaches. My probable diagnosis leans towards a Psychological factor, which can be confirmed by 2 things 10 all relevant investigations being normal and 2) Evaluation by a Psychologist. Investigations:*Routine blood investigations like Complete blood picture, blood sugar, urea, creatinine, liver function tests, thyroid function tests.*Urine -routine and microscopy*Stool: routine, microscopy, occult blood, culture and sensitivity.*Ultrasonography of abdomen, *Colonoscopy All these investigations should be within normal limits for one to say you have IBS. A trial by a Psychologist / Psychiatrist may be of help and the response with his medicines can be confirmatory.
