1. as you have not been examined or undergone any investigations thus causes will be directed towards "pain in ovary AREA". [ovarian cyst
2. because symptom(s) are persisting from 1 year, thus chronic pain
3. your General Practitioner will diagnose ovarian pain
depending on the suspected cause.Your GP will take your medical history, carry out a physical examination [pelvic], investigations [ultrasound,blood test
,hormonal profile] and ask relevant questions about the pain.
PS: although ovary is located in this region, so are other organs, such as bowels, so IBS [irritable bowel syndrome] can be included.
