My teenage son had a long drawn out illness, earlier this year, marked out by persistent migraine type headache, achy neck and fatigue. Doctors put it down to glandular fever type virus, although it was not glandular fever he had a persistent low white blood cell count for 3 months whilst suffering with frequent relapses. Eventually he got better and no more symptoms. A week ago, he was floored with the same symptoms again, and has been in bed ever since. Doctor prescribed beconase for sinusitus, which he has taken for a week, no effect on headaches. He has also got a sore throat and back of neck. Pain killers have no effect on headaches, including co-codimol. They do work with some of the other symptoms such as the neck ache. My brother, a consultant Dr, thinks the headaches are migraines, but he can't explain the persistency, but thinks they need further investigation. Should I be asking for MRIs or other scans or even bone marrow test? Or do I just wait it out for weeks until he recovers again. if it is just some mystery auto immune virus. of course his school work is suffering.
