Why would they do it on purpose?
There are very few problems out there that have no name.
Maybe your doctor just cannot find anything wrong with you?
As already answered, any doctors or consultants opinions are sought before your assessment. The assesing Dr has nothing to gain from underscoring you - they are not on some kind of target bonus.
If your own doctor thought you had something serious, tests would have been performed earlier on.
I can sense that you think everyone is against you but I'm sure that's not the case. The DWP need to cut down on people claiming Incapacity Benefit therefore if you are fit for work (even if it is not your normal job) then it is there job to say so.
Good luck
