Hi thanks for your question
You have post hysterectomy bleeding after 2 years.
There should be no bleeding after even
partial hysterectomy, if
uterus is completely removed and only
cervix is left, as usually happens in partial hysterectomy.
If you had bleeding during early periods of hysterectomy, one can presume that some portion of uterus containing endometrium is left during partial hysterectomy, which is bleeding.
Since you didn't have bleeding for two years after hysterectomy, that factor is ruled out.
The most common cause of bleeding this time could be
cervicitis that is infection of cervix.
The second cause could by malignant changes, as post hysterectomy stump carcinoma is well known entity.
You can discuss this issue with your gynecologist.
Change in gynecologist is your personal choice, if you’re not satisfied with your Doctor, it is your right to have second opinion
Treatment of bleeding depend upon cause.
Blocked tubes and overlain cyst if small in size don’t bother, follow them on regular
ultra sound,
Hope information I provided will be beneficial to you
