I was very impressed when one of the National trust team of volunteers mentioned a sting treatment that seemed to sort the unpleasantness quickly and effectively. Eventually I remembered to ask Elizabeth what it was called and purchase some – it is called After Bite and does seem to smell of ammonia but that is the only disadvantage mentioned. Her comment was that she had tried creams but this pen was the first thing that seemed to work for her and it had helped her grandchildren, too. It is more of a pen (but not an epipen). I wouldn’t say I am looking forward to a sting but I am more confident armed with this.
