hi micmash and welcome to the board.
this is a great place for information and support.

it's been 7 yrs now since i was dx'd (diagnosed) with MS. i remember how it felt to make appts, wait for the appt, wait for the test results etc.

however, it doesn't help to get so stressed that it's affection your health or life. it won't change anything because you have to wait anyway.
i would try to take one day at a time. read a book or listen to music.
also, keeping a sx (symptom) journal with the dates and sx's you have may help your dr when you meet with him.

think of Q's and write them down. try to have a family member or friend go with you for support and an extra set of ears.

what i'm trying to say is that if you can gain some control of your fears you will hold onto your personal power. don't give it away to fear.

also, get copies of the CT scan. your neuro may want to see it for himself.
i hope your appt goes well and you get the answers you need.
please con't to post as we are here for you for support.
