hi, ur first history indicates to the diagnosis of 'scar endometriosis'. u need a consultation to gynaecologist, she will perform some tests and will tell u about the treatment options i.e. with the medication or surgery.
about ur second problem, i would like to know ur age first. again a consultation is needed to rule out a mass at the cervix
or vagina, that might be obstructing the flow, or it may be due to any other cause or functional.
