I had a spinal tap on Tuesday, to determine if I truly have pseudo-tumor cerebrum. They tested the pressure of the fluid in my spine, and withdrew a sample for testing certain levels protein and such I guess. The doctor said that many ppl with this condition are alleviated of symptoms simply by the procedure. If it stops the swishing in my ear I would be happy, but I have a headache today and I had one yesterday and one the day of the procedure. I think there is a multitude of things going on with me and my head and this pseudo-tumor is just one of them.
