the recurrent headache you are having looks more like tension headache
due to stress. but i cant rule out migraine
. it would be migraine if it is one sided, if it gets triggered by coffee, loud noise, etc.
but i think you are stressing yourself too much. the hair fall
could be due to stress and tension.
i would advise you to consult a physician and get some tests done like complete blood test
etc to rule out anaemia
, and other tests for probable diagnosis like migarine for headache, achlasia as you have difficulty to swallow etc.
if all the tests come out negative then you will have to get treated for anxiousness which will help relieve you of your stress. have a good balanced diet of fruits and vegetable. exercise regularly and try not to worry too much.
i hope i have answered your question.
