What causes neck pressure and stiffness, headache, leg spasms and light sensitivity?
Further examinations needed.
Hello and thanks for using HCM.
I have read your question and understand your concerns.
Symptoms your refer about are more probably related to TIA or transient ischemic attack that may have been evolved to stroke.
Brain CT is not the choosen tool to evaluate these conditions especially in first hours, brain MRI is the best imaging tool about diagnosing these conditions.
Neck vessels should be evaluated too, about stenosis, or in rare cases after neck physical therapy procedures, artery dissection should be evaluated as well.
High blood pressure and high blood lipids should be assessed and treated.
In conclusion, discuss with your friends's treating Doctor about having done brain and neck MRI/MRA, and a neurological examination.
Hope you found the answer helpful.
I remain at your disposal for further questions and clarifications.
