Hi Southern_mom!!! First i have to say that what kind of Doctor gives a MS diagnosis right away?? good that youre family said that it wasn´t good enough!! I have Familial Hemiplegic migraine ( runs in the family) and they can see it in a geenetest, but there is another kind of HM it´s called Sporadic hemiplegic migraine then they ca´nt see it in a geentest but they have the same symptoms.
Often the neurologists have never seen a patient with HM beacuse it´s so rear, so maybe he didn´t new so much about it?
many of us have had too wait a long time to get our diagnosis, my neuro told me that they ca´nt put a HM diagnosis before they have ruled out other diseases that gives the same symptoms and that you have to have had at least 2 attacks, the main thing in HM aura is that we get the paralysis, you wrote that you got a heavy arm then. I think that it was heavy beacuse it was week a little paralysed.
But no one here can tell you if you have HM or not that can only a specialist do, so if i was you i should look for a migraine specialist .
And another important thing write it down on paper what happened how many hours or minutes or days you had that and that symptom, beacuse it´s so easy to forget things when you sit at the doctors office and are about to tell him everything.
I am 45y and have had " normal migraine" without aura for over 20y, but in 2006 i got paralysed and then my hell started had HM attacks many times a week with soo many different symptoms ( the same as when you have a stroke) So...yes migraine often changes for many of us.
Good Luck and keep us posted if you are wondering about something!! Sweden
