I went to urgent care this morning as last night I had what looked like a white blister between the fourth and fifth digits of my toe on my left foot. He took a culture and I m waiting for the results. He said it could be either herpes or shingles and started me on two medications: clindamycin and valacyclovir as it hurt a little and the red rash was spreading. The rash has not spread but my foot started swelling up tonight. I am elevating my foot and icing it. Is there anything else I should be doing? I m taking the Rx s as prescribed.
