I got stung by nasty little wasp on my leg on Friday, it didnt hurt at the time but has become swollen and now right where the sting was it looks like a tiny blister, around that its now bright red and really angry looking, about the size of a satsuma, its swollen and the skin is really tight, around that its pink, in total the affected area is the size of a saucer, towards the end of yesterday and today it begins to hurt and I cant walk properly. Is this normal for wasps stings or should I see a doctor if its still like it tommorrow. Probably sound a right old baby but we are off on our hols next week and I dont want this to be a problem.
