Thanks for posting this question in HCM
First of all let me tell you that a given medical problem can be due to various causes. Headache can be due to various causes too. It can be due to brain tumor
, infection, problem in the blood vessels of brain, migraine
and so on. Whether a patient with headache will require a brain scan largely depend upon the presence or absence of neurological deficit on neurological assessment by a neurologist
The constellations of symptoms that you have provided and the bleeding and low white counts are the points of concern to me. You need the following things.
1. assessment by a physician who will determine if you have any neurological deficits or not and if a brain scan will help or not. But i strongly advise you to get a scan
2. You need a detailed blood counts which will tell if you have a generalized tendency to bleed or not
You need urgent medical evaluation without delay. Your treatment will depend upon the exact diagnosis rather than assumption.
Hope this clarifies
