Thanks for your query. These unusual perceptions/feelings like cold/hot flashes, tingling sensation
and ringing sensation in ears are likely to be part of aura associated with migraine headache
though the location of headache does not fit into typical migraine. I would suggest you undergo an evaluation by a neurologist
to clarify the diagnosis further. If neurological evaluation is normal, i would suggest a thorough psychiatric evaluation for anxiety disorders which can present with similar symptoms. Wish you good health.
