i have posted this in another category and it brought me to a question
relevant to this category.

"I have been to my GP, neurologists.... everything to no avail. About 4
months
ago i started experiencing a central, dull headache. Now this was the only
problem for about a month... one morning i woke up and my headache was
accompanied by a really disorientated, spacey feeling... its hard to explain :

Its really hard to concentrate, mentally slow, feel really spaced out i go
into my own little world and i believe i lack normal levels of emotion. This
has gradually gotten worse and persisted for the past 2 months. Ive recently
had a consultation with a neurologist and an MRI: MRI come back clear apart
from some abnormality which the neurologist thought was more consistent with
'mild ectopia' then 'chiari malformation' - whatever they are. The
neurologist prescribed me with an anti depressant which is apparently also
used for headaches (amitrip) which has done nothing.

This may be of significance... in early 2004 i was working with leadbased
paint extensively for 3 weeks, not knowing the dangers. Apparently it was
'red led'... i was breathing this stuff in heavily everyday for these 3 weeks
and i noticed a metallic taste in my mouth during this time.

Also at the start of the year before these headaches started to occur i had a
blood test which showed inadequte levels of vitamin B12... this may also have
some significance?"

Someone said that a lack of vitamin B12 may not be the problem, and that its
possible that it  could be a result of LEAD POISONING. I assume i was
diagnosed with a lack of vitamin B12 after a low red blood cell count was
recognised after a routine blood test.... could it be lead poisoning that
caused this instead?
