Thanks for the query.
Some amount of pain is common after abdominal surgery
due to the possibility of adhesions.
Sometimes induration can present around the wound area giving rise heavy felling.
If you underwent bilateral salpingo-opherectomy also along with hysterectomy
then there is possibility of hormonal
imbalance which might have responsible for you breast symptoms.
So you better once consult your gynecologist and go for hormonal replacement therapy if she suggests.
