Hi,
Welcome to health care magic,
The infection after any surgery can cause close-cavity infection.
It could be close-cavity infection on the right side above the pelvic bone.
I would suggest you to undergo urgent high resolution
ultrasonography to watch for an abscess; if present re-exploration is the best way to drain the abscess and put in a drain to avoid further complications like
septicemia and
bacteremia.
The terrible pain is again suggestive of an active inflammatory process.
So,you should go for complete blood picture,
kidney functions tests, blood sugar fasting and post-prandial blood sugar.
Urine- routine,microscopy, culture and sensitivity can also be done.
This will certainly help you to recovering faster and completely.
Pus culture and sensitivity has to be insisted upon.
Consult your operating gynecologist for further advise.
Regards,
