Suggest Treatment For Vertigo And Pressure In The Head
Further investigations are necessary to get a clear diagnosis.
Detailed Answer:
Hello and thanks for using HealthcareMagic.
I have read your question and understand your concerns.
Since two courses of antibiotics still didn't work, imaging of the head and brain of your brother is necessary to evaluate any sinus or middle ear infection, and, if this will result true, spreading should be evaluated also.
CT scan or MRI brain are necessary for this purpose.
Cultures of sinuses secretions about the causing organisms and sensitivity toward antibiotics also should be assessed too.
Please discuss with your brother's primary care Doctor about these issues.
Hope you found the answer helpful. Let me know if I can assist you further.
Take care.
