Sir, my sister always keeps smiling & is my dads darling daughter whose all demants r fulfilled..She under went with an abortion 6months back.. 2months back again wen she got to knw abt her pregnancy, she got it terminated by consuming pills.. She has a habit of daily washing her hair nd recently went into a little depression for not able to clear her ielts exams.. Now, its 25days passed nd she is out of it but everyday evening she starts having severe pain at the back of her head.. Plz tell the reasons behind this headache.. We consulted many neurologists Bt no body is able to find out the cause.. Thankyou
