Yes, that's pretty straining to have to wait until August. That's due to the Canadian system? Very bad considering the problem you have, but remember that even the MRI may not give a definite dx. And I'm surprised about the steroid comment, since some other diseases indicate steroids would help. Like Ann, I traversed long through many neuro symptoms before an MS dx, then a Porphyria dx. I had symptoms at age eleven which went away, then again as a college freshman, then again...over and over...no dx until middle age.
