Fungal Meningitis

[oliverm]

Over a week ago I moved into a new room and did something really stupid; I shut the ventilator in the shower room and proceeded to have really hot showers every night without opening the window. A week later mould started to debelop and a funny smell. I slept without caring about it until one day I woke up with a small fever. The next day I felt really really weak and then the 2 days after I gelt weak then I developed a very stiff neck. I went to the hospital and they performed bloodwork to look for infection. I told them I feared it was Fungal Meningitis but they did not perform a spinal tap stating the risks.

I want to know, given that the bloodwork came back normal; should I have demanded a spinal tap anyway?
