Hi. Last time I was at the dentists, she rubbed 'numb cream' into my gum before the injection, which helped quite a lot. I said that something like that would be great for small children who have fallen into stinging nettles or somesuch, and she told me that it does exist and you can buy it at the chemists. However, when I asked at Boots, the assistant had no idea what I was talking about. Has anyone any ideas on the subject?
