Do they still even use penicillin these days? I'm supposedly allergic to it and have no memory of how or why I was told that at a very young age. Same. I tried climbing a phone pole when I was six, got a huge splinter under my middle finger (still have the scar) so I saw the doctor, supposedly, and got a penicillin shot that gave me a bad reaction, and I've been telling people for the past half-century "Penicillin" when they as about allergies, though I don't remember any of this, just a story (and as scar) I've been told about. "What was the bad reaction, exactly?" "I was six, and out of my kug with fever, probably, how the hell would I know?" Same thing here. Allergic to "Ceclor" and have no memory of having it as a kid.
