Hello--I am so sorry you are having a non-stop problem with headache pain and nerve sensations that can feel "scary."  Just wanted to add to what Nancy said--when  you see a specialist take in a list/calendar with you whereby you have analyzed and recorder for each day, things like:  time of day you have headache pain; time of day you feel the nervy feelings in your scalp;  note when it started relative to when you began the Antidepressant (some of your feelings could be related to a medcation side effect, not the headache, but only your MD can sort it out).     Write down the times of day or night symptoms or pain get worse, and note any triggers (foods, weather, light, etc) that exacerbate your symptoms and WHEN during the day these occur.  This will help your MD make a faster diagnosis, and hopefully lead you to sooner relief.  Note also when these occur relative to your menstrual cycle, if relavant.  Note when you have not had good sleep, record your level of exercise, ANYTHING that might be playing a role in your symptoms.    I have that "whoosing" noise with my headaches, particularly when I bend over.  I have hormonal migraines and another type of headache called "hypnic" headache that really causes a very loud "whoosing" noise, so much that I cannot hear.  My headache doctor helped sort this out.  So a headache doctor (if your neurologist cannot sort this out) is needed to figure out exactly what is causing your symptoms, and to make a proper diagnosis in order to select the best treatment options.   Somewhere on this website there is a recommended "calendar" and symptom log to assist you in mapping your triggers and analyzing the timing of  headaches and other symptoms, but I do not know how to find it (I just tried).  I'm hoping someone more conversant with the site can tell you now to find it.  Good luck and I hope you feel better.
