http://www.medhelp.org/posts/show/13154

Please help us - what is this???  I also have the same problems, have just had 11 lesions found in my brain but no definintive dx (just dx with tmjd but have no pain except for the rare headache) - it's this PRESSURE when I stand up or walk - but sometimes even when laying down I get the pulsatile tinnitus.  I have low blood pressure normally - used to feel faint when standing up too fast - now can't get up that fast - but get this pressure instead anyway!!!  HELP US PLEASE!
