Hello!
Thank you for asking on HCM!
I read your question carefully and understand your concern.
His past history of cocaine intake is really concerning.
I would like to explain that cocaine intake is related to different complications (such as
high blood pressure, brain vessel disorders ),which cause headache.
Have you measured his blood pressure?
I recommend consulting with the GP as soon as possible for a careful physical examination, a routine
blood test, inflammation tests (fibrinogen, PCR, sedimentation), blood electrolytes,
kidney and
liver function tests.
It is important to closely monitor his blood pressure.
A transcranial Doppler
ultrasound of the brain vessels and a brain MRI may be needed to exclude the above disorders.
Hope to have been helpful!
Best wishes,
Dr. Aida
