What causes head discomfort and dizziness?
Patient: For a few months I’ve been experiencing the feeling of something wriggling in my head/brain like a worm sometimes it hurts but since it started I’ve had nothing but dizziness and waking up and feeling sick all day I wondered if you could help me figure out what it could be Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  Several things would have to be known about your condition...your ORTHOSTATIC BLOOD PRESSURES, ELECTROLYTE LEVELS, HORMONES, LIVER and KIDNEY function tests, and CBC with differential.  You may have an infectious process, a condition known as BPPV, or there could be a spontaneous CSF leak (common in people who wake up with severe headaches with and without spinning sensations).  Hope I have answered your query. Let me know if I can assist you further.
