It could be a painful ovulation. They usually are very painful in patients with endometriosis
. There can be some gastrointestinal dysorders as well (they quite often coexist with endometriosis). I think in your case some analgesics and nonsteroidal anti-inflammatory drugs could be prescribed. Actually special treatment for endometriosis has to be prescribed which can be combined with phytotherapy
, etc. You could also be undergone laparoscopy
to remove all endometrioid heterotopies.
Wish you Good Health
