Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
In background of such surgeries if you are feeling swelling and discomfort then it may be due to presence of infection .As this swelling and discomfort is also not relived by anti inflammatory medicine so you should see ER for immediate relief. In case there is an infection, an appropriate antibiotic has to be instituted right away and hence going to ER will be a logical choice.
Hope this will help you.
Regards.
