skin or soft tissue infection
"I was prescribed Cephalexin for a soft tissue infection in a finger. The drug did in fact, reduce some of the swelling. However, generally speaking, my reaction was not what I would label as positive. After the fifth day of a seven day cycle, I woke to find a major outbreak on one half of my face. On a sidenote, I was prescribed Tetracycline as a teenager for acne. And what I woke to was a flashback of early teen acne  Regardless, I brought it the attention of my healthcare provider. The general response was......nothing. The nurse, the doctor, the PA. None of them even reacted, much less responded to my concern. In the end, I have had a serious acne outbreak at 53. Appears I am allergic to Cephalexin."
