Thank you for your question.
The symptoms of headache, fuzzy vision and disorientation
may be indicative of infection like meningitis
. Low appetite, fever and back pain are other associated symptoms. A detailed clinical evaluation by a neurologist
can diagnose this. To find out the causative organism of infection a lumbar puncture
is done and sample is sent for cultures and staining. Appropriate antibiotics are needed to treat the infection. He needs to see a doctor as soon as possible.
Wishing him the best recovery.
