There are many potential causes for pelvic pain. You will need to see your primary care doctor
or your OB GYN doctor to help you figure this out.
Endometriosis is caused when tissue from the uterine lining escapes out into the abdominal cavity and grows. This can cause pelvic pain, usually that cycles with the menstrual period, as well as heavy periods, bloating, and other symptoms.
Other causes of pelvic pain can include uterine fibroids, which are benign muscle tumors that grown in the uterus, causing cramping, pain, and heavy menstrual bleeding
Sexually transmitted infections such as chlamydia and gonorrhea can also cause pelvic pain, especially when they ascend into the uterus and fallopian tubes, causing an inflammation know as pelvic inflammatory disease.
Pelvic pain can also be related to other symptoms, especially the gastrointestinal system. For example, constipation and irritable bowel syndrome
can both cause pelvic pain.
As you can see the list of potential causes is long! Therefore you will need to see your doctor. They will ask more questions and perform a full physical examination including a pelvic examination. This will allow them to narrow the list of potential causes and help you decide what further workup is needed.
