It seems from the history that you are having numbness, tingling on left side of face and blurring of vision. These symptoms indicate migraine headache
The treatment of the condition is by use of analgesics and anti-inflammatory drugs in the acute episode.
However the recurrent attacks require use of prophylactic drugs like flunarizine
or beta blockers like propranolol
Hence your GP has told to consult neurologist
for prescription of drugs.
