Hi--My aunt is 98years old and has been diagnosed with cellulitis. She has been taking Clindamycin 300mg, as prescribed, since 5/16/2016. Her feet are terribly swollen, red, and have become very itchy. I this due to the Cellulitis or the medication? If the medication, should we contiue to give it, even though there has been very little change, or contact the hospital that prescribed it?
