Marcin,
I hate to see you torturing yourself like this. Supposing you knew someone who had headaches and they saw several neuros. All their tests for things like brain tumours were negative and all the neuros told this person that they had stress-related headaches.
This person then gets so worried that they have a brain tumour that they start visiting websites and discussion forums run by people who have brain tumours instead of sticking to sites run by people who have stress-related headaches. What would you advise this person to do?
There's no point visiting those scary als sites because you DON'T HAVE ALS - you have bfs. So if you have a rule that you stick to this site and stay away from scary als sites then you won't be so terrified. This site has all the info you need!
It's much more straightforward for a neuro to tell if someone does NOT have als compared to confirming the diagnosis if they DO have it. For those who do turn out to have als, the neuro can almost always tell straight away that something is wrong. It might take a long time to confirm the exact diagnosis, but they are not in the business of telling people they do not have something when there is a chance that they might.
I hope that this helps,
David
