Hello dear friend, I understand your concerns.Migraine has a few hallmark symptoms for diagnosis.They are- Usually episodic(becomes chronic in late stage) On one side of the head,but often changes side in different episodes. Pulse like throbbing headache Associated with nausea(vomiting sensation but not vomiting) in 85% cases,but vomiting in only 15%. Increased pain on exposure to bright light and loud sounds. Aura-visual abnormalities like flashing zig-zag lights,able to see half alphabets or letters,blind or dark spots in field of vision,distorted shape of objects or other visual abnormalities. Precipitated with trigger factors like stress,bright light,tea,coffee,cheese(you yourself has to find the trigger,if any in her case.It can be almost anything,she relates the headache with.) So,look out for these things and it will give a clue whether it s migraine.If any problems,revert back to me.I hope it was of help to you.
