skin or soft tissue infection
"Penicillin VK did -0-; Keflex cleared up a BAD infection from getting a 2 inch splinter out of the upper half of the bottom of my foot. Side effects were miserable: PAIN, fatigue, constipation; now 6 days since last doses. STILL, Keflex cleared up the infection that had a BROWN/YELLOW discharge. A STRANGE antibiotic, but I'd rather have pain than cellulitis."
