Hi Freesia38,
Welcome!
I know health programs in your country may be different then some of us have in the US. But I do feel that if your doctor was treating you for probable MS, then he did not test well enough, nor give you enough steroids. Perhaps it is something else and you will be happy it is not MS.
My brain and C-spine were clear in an open-MRI. Then the MS specialist in NYC, ordered a closed one. It showed plenty of brain lesions. Later on I showed one brainstem lesion and one at C-2 or C-3 lesion I believe.
It takes time to get a diagnosis for any Neuro disease or disorder, so you might have to see how your body is over time. He will probably check you again in a year unless you have more problems.
Call him or get another doctor if you don't feel he has helped you, or if you have any more problems. Get all problems documented by the doctor and treated with something so you do not suffer. Good luck to you.
