My daughter is 14, 3 or so weeks after her 2nd shot she got a yeast infection that would not go away, she also go thrush at this time because the yeast in her body was so bad. She got her 3rd shot the in Sept 2008 and on Oct 26 th she got virus like symptoms with headache nausea dizziness tunnel vision that will not go away. She has had an MRI, CT scan, blood work and been to the hospital 3 different times for fluid due to the nausea. The neurologist says that it is a migraine that is not responding to medicine. but I wonder now if it could be due to the shot.
