It's not my story, no.
I don't know whether I still have HA, probably a little. Certainly not like when I was panicking and convinced myself I had MS, back then the symptoms were overwhelming and I just stopped functioning. I made the transition from a fully sponsored postgrad researcher in a science subject at one of the best universities in the world to a bum within two months. I'm now nearly back where I was, luckily.
She was misdiagnosed because she had a single migraine lesion, and also this was going back a couple of decades (so the same mistake probably wouldn't be made today). She doesn't have MS. They are different illnesses with (as with all neuro disorders) some... significant overlap in symptoms but no overlap in presentation of symptoms. Note the crucial difference here.
I'm just making the point to you the danger of hanging around MS forums where the only person who thinks you have it is you. They will only serve to reinforce your fear.
In terms of my own symptoms, I still have fasciculations and transient tingling. I have the constant pressure sensation on top of my head (though is mostly settles on the right these days), though this is always relieved by my osteopath (I must go back soon, I've been busy). This is because my neck muscles are really tight (bad posture, stress, whatever), which has caused a couple of cranial nerves to become irritated. (In my BFS, any nerve entrapment is amplified massively).
I really do understand where you're at. I've been there. I had symptoms and I researched on Google (I am an academic after all, I should be good at this) and Google told me I had MS. Everything I saw confirmed it. I saw a neurologist privately, I saw the very best, and he told me I definitely did not have MS based on symptoms alone. I then over the course of eighteen months, thanks to the NHS, saw three different neurologists at the best specialist neuro hospital in the country, and they did lots of tests, and before and after every single one of these tests they told me the same thing: I do not have MS. Luckily my EMG picked up (non-neuromytonic) peripheral nerve hyperexcitability (hence the BFS diagnosis).
Please don't make the mistakes I did. I can't tell you what you do and don't have, but I can tell you by having pretty much the same symptoms as you and more I managed to take the same route you seem to be taking to convince myself I had MS, and it nearly ruined my whole future and my life. Ironically when I consulted the real experts (four of them, no less), it was abundantly clear to all of them I did not have MS.
