Must admit, I think this is appalling.
To be given really important, what could be life changing, results by letter and email is just wrong.
Even if you can’t go into a hospital to have a face to face meeting. Surely you can have a telephone conversation.
The letter and email will throw up lots of questions that you won’t be able to get answers for.
I presume you have symptoms of MS.
Positive result - what happens next? DMD?
Negative result - what’s causing the symptoms?
Just hope you get the email soon then at least you get an answer and can contact medics.
I’d book a Dr appointment tomorrow. So at least you can talk to someone and get referred to a neurologist if needed.
Let us know.
Good luck and a huge hug.
