Wow!
No wonder you are so scared - I can't believe that your chiropractor has made this call. I also can't believe that the girls you work with are that nasty.
Others here have given you great advice, Kicker has called the gods to smite those who are being so mean

, and we all agree that MS is a complicated thing that will take some investigating before diagnosis.
So....take a deep breath...this is a great place for friendship, support and information. If you do end up with MS - life will go on. Some things will be different, but there are many worse things that you could have, and there are amazing strides being made all the time across so many medical frontiers.
Please take care, and take heart - you are not alone, so keep us posted.
