I have for several years tried to explain to my docs that I get what I call brain explosion (if you put your hand tight to one ear then pull it off suddenly that noise and feeling it makes) followed by vertigo. Sometimes full spin other times like being on a boat on the ocean. They all say they never heard of such a thing. I do have M.S. and have had a head injury that seems to start it all, i.e. M.S. and brain explosions with vertigo.
Good morning. I believe I understand your symptoms urologist and especially with what you describe is not that uncommon and certainly not that unexpected for someone with a diagnosis of multiple sclerosis. You could have several types of phenomenon that are happening. Some could be related to a headache type of picture while other possibilities include brain lesion that movie present when I fibular or auditory pathway and cortical regions of the brain.  There would be several questions that I would want to ask you and other information to obtain which is much more complex than what can be written in this short space. If you would like to write to me for a specific consultation request I can give you more details and help you understand what could be going on.  bit.ly/ Chat Doctor.
