DH; Headache or brain tumour?

[landj]

My DH has worked nights for 2 years. Recently he has been suffering from (his words) a woozy head. Symtoms... Pressure in ear drums, swimmy head, feels like his movements are slower. Feels clammy and short of breath. When he turns his head feels like his eyes take a while to catch up. This is consant. everyday for past 4 weeks. Blood tests showed nothing. Im sure its stress and tiredness. Any ideas or similar problems?

Inner ear infection?
Although that doesn't count for the shortness of breath and clamminess.

middle ear actually

my mum had it ,felt awful for weeks
