Hi Cheryl . I am sorry you developed those headaches and the vomiting makes it all the more worse .I know about the vomiting issue but mine was not T.N. related . I think having a MRI was a very wise thing to have done and also going to headache doc . perhaps it has to do with blood flow at night when your are laying down is different then when you are up durring the day or sitting ect. make sure you write down things to bring to your apt. write down when you get them time of night what it feels like what position your in ...ie laying down on back with head propped up on pillow or sleeping on stomach with arm under pillow or how ever . Notes really do help even though it may seem silly it is not. I wish I could help you more but the only thing I can do is try to send a couple people who have had MVD to post here and also if you have not read Ellas MVD diary it is at the very top of this page her email is in a post on page 2 feel free to contact her. Let us know how things go and I am gonna try to get one whose had MVD to reply. Sending low pain thoughts and hope your coming apts bring answers and simple solution to those headaches .
Peace
