The doctor should know what type of blood tests to give. Be careful, some doctors do not like when you show up and telling "them" what to do.
Crystaly .. I feel for you, I really do. I too have many neurological symptoms that dont tie in. Like yourself I have had an MRI brain scan, blood tests and nerve conduction tests (all normal).
My symptoms are all consuming and have completely dictated for many years what I can and can't do in life, e.g. sudden staggering to my lefthand side when im walking, sometimes not being able to walk in a straight line, almost total exercise intolerance, eye muscle twitching, tingling/prickling/itching sensations over my body, involuntary limb movements, eye and cheek bone pain, a feeling of heaviness/weakness on my left hand side, sudden feelings of shock/fright which take my breath away, mental impairment, confusion (not knowing where I am), feelings of pressure inbetween my shoulder blades, ringing in my ears, sudden crashing tiredness which I could almost describe as passing out .. the list goes on.
I have decided just recently to have a look at nutrition, as I probably don't eat as well as I should (but I don't eat badly either) and will be making an appointment with a nutritionist very soon to see if they think some of my problems could be to do with nutritional deficiencies.
I do hope you find a solution to your health problems very soon and I wish you well.
Hm that comment from the neurologist is interesting. My husband has been undiagnosed for 10 years and has been told that he has TOO MANY symptoms that don't add up.
