Hi, Thank you for your question. Common symptoms
could be unconsciousness, loss of vision, headache, eye and neck pain, seizures, paralysis, gait disturbances etc. It needs some days to recover completely as it depends upon severity also. Investigations like CT angiography, MRI, CSF examination (presence of blood) are essential to reach at diagnosis here. Neurosurgery is the mainstay of treatment that may be suggested by a neurologist after examination.
