Good Afternoon. As A Child, I Was Told I Had

Good afternoon. As a child, I was told I had an allergy to penicillin. A few years ago, I had a horrible reaction to vancomyocin (no idea how to spell). Immediately flushed with red man syndrome. I am now almost 50. Last week, had an infection and got an antibiotic called CLINDAMYCIN. I have been feeling like my esophagus is on fire,,,,,like a mild heart ache....I just put it together that the medicine might be the cause. What do you think. Kathy.
