My 15 year old daughter has been vomiting between 10 and 50 times daily for 8 weeks now. She has had many tests, including, chest x-ray, upper, and lower g.i., MRI, CT, EEG, ultrasound, scope test, blood work, urine tests, and digestion pictures (forget name of this test). Every test has come back negative. Her symptoms are chest pain, dizziness, occassional fainting spells, headache, abdominal pain, and of course constant vomiting. Doctors have no idea what is wrong with my daughter, and have discharged her although her symptoms are still as bad as ever. It is only 1 p.m. here, and she has already vomited 23 times. She has had no change in lifestyle , or any recent trauma, under no stress...we truly believe that whatever this is is a physical medical problem, and not psychological. I have done research on Cyclic Vomiting Syndrome, however, she has had this problem ongoing for 8 weeks, and has never experienced anything like this before. Help please!!! Any suggestions or ideas are greatly appreciated. Thanks.
