My son was diagnosed with staph yesterday.  He has two locations, one that was large, dark red and filled with pus.  The doc lanced and drained it and put my son on antibiotics.  He took one last nite and two today but he is still in a lot of pain and running a slight fever.  It almost looks like a hole in his leg.  Can I wait till the AM to check back with his doctor?
Hi, Welcome to Chat Doctor! Since the infective organism has been identified (Staphylococcus), your treating doctor must have given the right antibiotics. So you need not worry. Since the lesion was big, it was necessary to Chat Doctor.  Antibiotics will take 3-4 days to show their effect. Meanwhile, I'd advice your son to take an antipyretic and painkiller to get relief from the fever and pain respectively. Apart from this, you may wait till AM. Hope this has solved your query. Feel free to ask for any doubt.
