I had a card accident two years ago hitting my had severily in the steering wheel. since the accident I have been getting headaches, terrible nausea, flu like symptoms and extreme fatigue. The blood tests do not show anything. ihavw had an MRI and its normal. i went to a couple if neurologists and they said im neurogically ok and they do not want to do a lumbar puncture. every couple of months my symptoms get worse and aggrivated if I do something too strenuous. If i get a simple cold i suffer for two weeks with fevers and it takes so long to recover. Could it bE that I got a small fracture in my skull from accident allowing bacteria to pass through the cerebral fluid making me sick? please, if anyone has had a similar experience can you share?
