Hi, I went to the Dermatologist on Thursday (3 days ago) and was diagnosed with cellulitis on my chin. She gave me Clindamycin HCL 300mg every 6 hrs. I have taken them since Thurs. afternoon, so like 12 to 13 pills. The rash looking redness is gone, low fever is gone, heat from the lump is gone. However the lump seems harder (is about the size of a large egg, 3 inches long by 2 inches wide). She wants me to follow up with her on this coming Thurs. and said go to ER if gets worse. If it s getting harder, is that it getting worse?
