I think you should trust the professionals you’ve already seen. When my horrible twitch lasted four lousy months, I was going nuts. I too have health anxiety as you know! I simply went to an optometrist. Unlike you, I avoid medical professionals but I have the same anxieties. So I took his word for it. (Well kind of, I wanted to believe him it was easier than traipsing around neurologists which I’d find terrifying. Same phobia different behaviors! I avoided that since it would have stressed me out even more than I am already!
The point is, if I had seen all of those people and they had said everything was OK, I’d have been glad and relieved but you aren’t. Which seems like you want to keep the ball of fear rolling. However, I know it is the most horrid feeling ever when it twitches simply because your hair blew into it.
The real issue is anxiety perhaps you are using the doctor visits and fear to avoid facing that which really is the issue and that is facing what your anxiety is really about. Often doing something physically inane like seeing loads of reassuring doctors can distract us from our inner selves. That’s why we do it.
A good therapist will guide you into looking at all the real noise inside of you the one you are avoiding and trust me, it’s not that bad, you won’t break up into zillion pieces or if you do, a good therapist will piece you back together again.
Someone said to me the other day (and it is merely an opinion of this person not a fact), that every time we experience trauma we leave a little piece of ourselves there. Or, a piece of our soul (whatever you believe in). That part re-enacts that trauma over and over again. The more traumas the more phobias, or the bigger the trauma the bigger the phobia. The problem with phobias is that they grow branches and twigs and become so complex. However, the root is not too hard to find if you are dedicated. You are probably asking this over and over again to garner reassurance. Not real advice. If it were real advice you wanted you’d have listened to the neurologist. Something inside of you needs reassurance, something needs you to be able to reassure yourself.
By the way I am writing this lengthy ‘thing’ because I am also writing it for me, your fellow neurotic phobic! That was said in friendship not in a horrid way!!
You might have to go the botox root to stop the twitching if it bothers you that much, however, I think when you alleviate the cause the symptom will vanish. Mine twitches now and then, but it’s more or less stopped. It went on for four or five crazy months.
I hope you do feel better soon and I hope it does stop twitching soon, like mine did.
