Our son had what seem like a normal virus with fever,
vomiting and
headache. All symptoms went away except the
headache, which has persisted for a month to the point of excruciating pain 3-4 times a day. He had MRI, CT, lumbar puncture, blood work, etc. All came back normal except positive test for mycoplasma. The first hospital did his lumbar puncture incorrectly causing severe vomiting and spinal headache. That plus all the pain meds (toradol, morphine, atovan, etc.
