Welcome to the MS forum on NT, Mia!

I agree with Sally! Physical and emotional stress as well as an illness can trigger an MS attack, but not cause MS. I do know of one person, not on these boards, that had a severe accident such as yours. MS was diagnosed as an incidental finding. The accident didn't cause the MS and he didn't know he had MS, it just showed up in testing due to ongoing symptoms.

Please let us know how everything goes with your new neuro!
