Should i wait til tues to go see a dr or go to the er?

Already been diagnosed with a slight fracture and sprain of the ankkle one week ago, however, they completely ignored the 7 inch scrape on my shin. Now the scrape is puffy, hot to the touch, and oozing a thick yellowish green pus. Worried about staph bc I have a 2 yr old. Wait to see dr on tues, or go to the er tonight. (Sat)
