... placed on IV clindamycin for 3 days and the swelling dramatically decreased, and I was switched to oral clindamycin 300mg q6hr x 10 days. At this time a dentist opened up the cellulitis, irrigated it and stitched. There is no obvious lump on my cheek but with palpation there is still a hard cellulitis lump. No pus is noticeable inside. I followed up with a doctor today and I am now on clavulin 875mg 2x day for 7 days. Is it normal for this kind of cellulitis to persist for this long? Will it eventually go away?
