Thanks for the query.
As both your ovaries were removed there is less possibility of recurrence of cyst
You might be thinking the normal soft tissue
or fat presenting there as a mass.
But better to rule out.
So once consult gynecologist, get examined and if she recommends go for ultrasound
Some amount of pain is common after surgery due to presence of adhesions etc.
So you can take analgesics for symptomatic treatment.
