Hello!
I read your question and understand your concern.
Headache can be caused by sepsis , in cases of
meningitis or septic
embolism to the brain causing brain abscesses. It is not very common. But in both the situation headache would be associated with other symptoms like fever,
stiff neck , nausea, numbess of the limbs or seizures.
Taking
Rocephin may cause headache, but in cases of prolonged treatment , and you refer to have taken only for 13 days.
In my opinion this can be a New daily headache or a tension type, but we should exclude the above mentioned possible causes of secondary headache.
So I recommend you to consult with a
neurologist, have a good neurological examination and have other tests like a full blood work and a brain CT scan, if necessary.
Hope to have been helpful!
Best wishes, Dr. Abaz Quka
