Thank for asking to HCM
I can understand this the chances of migraine
is very less this could be functional kind of headache, most of the headache are functional they well responds to the symptomatic medicine and placebo too, if I would be your doctor then I would treat this case with the following medicines,
1) Tab Acetaminophen
three times in day
2) Tab chlorpromazine
10 mg three times in day
hope this information helps you have nice day.
