Other lesser-known signs of endometriosis for women to be aware of is back pain, abnormal uterine bleeding, chest pain or difficulty breathing.
Endometriosis is sometimes mistaken for other conditions that can cause pelvic pain, such as pelvic inflammatory disease (PID) or ovarian cysts.
It may be confused with irritable bowel syndrome (IBS), a condition that causes bouts of diarrhoea, constipation and abdominal cramping.
IBS can accompany endometriosis, which can complicate the diagnosis.
