Probably many Israeli female patients have heard the word: PMS [premenstrual syndrome], basically, all kinds of nasty feelings a woman can experience before the menstruation [you may read more about it on Wikipedia or else]Many suggestions possible [the Internet will be full of them]Today I want to mention a less well known[maybe rare] cause: a chlamydia trachomatis infection. This bacterial infection may cause many gynaecological problems even quite severe ones or possibly even symptomless [without symptoms]. If you found no solution for the problem ask your doctor to check for this or to give a trial treatment with doxycycline [doxylin in Israel]. [not in pregnancy] This is especially if the symptoms started after a first sexual encounter, after a D & C [“greida”] or after delivery etc.
