...true story:
Son worked outside for the weekend. Got jock itch. So went to drugstore and got some Hibiclens antibacterial soap.
Washed well with this.
By Monday he had a rash all over his body, and his balls blew up to size of baseballs....(I told him to post a picture on Tinder....)
and was getting difficult to walk,,,so he went to the ER, and got dosed up with steroids / steroid creams / antibiotic etc.
Apparently in some antibacterial soaps there is a component called chlorhexidine, and it has cause quite a number of adverse allergic reactions.
Told him to put a note in his wallet to warn any doctors / surgeons not to cleanse with anything but alcohol cleansers, and not to use any public soaps or antibacterial wipes etc.
He's much better now after.....thank goodness.
