That is news to me as well. I’ve used peroxide since the early 60s. I’ll have to get my brain wrapped around that one.
I have used diluted peroxide on my dog’s wounds in the past without problems, but the Vet said never to use it undiluted (very diluted). I would assume it’s the same for people. Instead of peroxide, now I use diluted Betadine antiseptic on the dog wounds and have even put a tiny bit in my Neti Pot for sinus issues. Peroxide is what people used WAY back when nothing else was available and it was cheap. There are better things now.
Thank you all for your advice. We will be taking him to a doctor when the clinics open tomorrow. It is almost 2200 here and so I am off to sleep. If you are a praying person, and I am, the child’s name is Sam.
For what it's worth, tetanus comes from horses. Had I known that, I won't have gotten a recent booster @ 69 yr's of age, and still welding.
