Your history is suggestive of some pelvic infection
probably related to the procedures during your last child birth; endometriosis
is another possible condition that needs to be ruled out. Please see a specialist for a complete evaluation. You will need a blood work up, urinalysis
and a trans-vaginal sonogram. Hormonal
profiles may be needed after these steps are done. Further management can be planned after proper evaluation, clinically and through investigations. Hope this helps.
