Suggest Treatment For Dizziness And Vomiting In A Child

my daughter has been having symptoms for a year and a half. she is very dizziy and nauseous . she explains it as being on a roller coaster on a swaying ,dipping boat. she was tested for heart, stomach, ENT, she works as a customer service rep for Progressive and has to use two monitors. this became a hardship as she had to keep moving her eyes back and forth prompting more dizziness and puking . they first ended up diagnosing her as having a pinched and damaged nerve at the back of the head. sent her to therapy , didnt help so much. gave her stuff for nausea . she is : severly fatigued, dizziness, spinning, cant watch tv for only about 10 mins. no computer screen, cant drive anymore. she then went back to Doctors and now say she has chronic migraines, silent migraines and gave her topomax and imitril. both of which make her exremely tired., changed her taste and she is very cold all the time now. she had bacterial meningitis twice . in 2007 and 2009. they saw two white spots on her brain, that didnt change from then till now. she had another cat scan done and spots didnt change, so they said its not significant. she is at at loss. if she cant get this under control or find out what she has, her job will be lost. she is on FMLA which safe guarded her job, but its soon to end. what other things can it be? one dermatologist asked her point blank if she had Lupus and the primary care doc told her no , becaues they did some other testing and if she had it , it would probably give some kind of sign and then they would do more testing. just upset . she is 29. andy suggestions you can think of, would help.
