Hang in there. I am just getting through the exact same fear... well still not through all of it but it's a little better. And, my experience was my panic (several attacks throughout this BT, other neuro problem obsession) brought on so many "symptoms." The perceived weakness I felt got worse. I even woke up thinking my speech was slurred (after my husband mentioned it as a symptom of BT that I DIDN'T have - he was trying to help me as I don't Google). I was waking with a headache every morning and would go to sleep with them every night AND they always seemed to be on my left side. I was in such a mess, I called my eye doc to confirm the date of my last eye exam. I felt good for like half a day as it was only this past March. Then I saw an actual neurologist two days ago. He went through a long list of questions (about my headaches) and the tested me with tools and all the other manual physical tests. He said (I didn't ask but I would have!) that he has no concerns of a BT or other issues. I said "you probably get the BT question often" and he said yes almost everyone asks him but in his entire career he's only seen 2 because they are rare and the 2 he did see were benign and removed. That made me feel better, too. Even though I felt reassured by the eye exam and neuro appt, I admit that I still think maybe I should have an MRI but have since just been repeating the mantra "Accept the diagnosis" over and over. Oh, and just in case this makes you laugh or just smile a little, the neuro diagnosed me with tension headaches, wrote me a prescription for Naproxen and asked his assistant to burn me a relaxation CD. I took it as a sign.
I also have TMJ (TMD whatever it is)... I am also chanting the same mantra with that one as sometimes I just can't believe that it could be causing all of my face pain, ear pain, scalp pain, neck pain and headaches among other things. An MD and a DDS said I have it. Do you think maybe you could be dealing with TMJ?
I can so relate to what you're going through. My anxiety and panic has made it so much worse. Are you on any meds? I don't like benzos but my doc prescribed me lorazepam at the onset of this current bout of anxiety attacks and when I take one, my symptoms almost completely go away.
