Hello doctor,I have a puncture wound that is very swollen and painful. Went to urgent care and they gave me an antibiotic. How would I know if it needs to be drained or not?
Hello. If it is swollen a lot with pus collection then it has to be  ChatDoctor.  Usually, it is visible outside and there is pus point called anabscess. Also, if it is not responding to antibiotics then we have to suspect the underlying pus collection and need investigations like ultrasound in those cases to confirm the underlying collections.  So I think, you should upload the picture for me to have look. Also, if puncture has happened due to metallic objects or a lot of wound contamination also request for tetanus shot if not had recently.  For more information consult a general medicine physician online  Take care.
