Piriton should be ok to take to help the swelling. Nasty creatures wasps. My OH says they have no purpose in this world, not sure if that is true but I hate them after my son got 17 stings when he was only 2 years old when he found a nest in our garden. It was horrific :-(
Two absolutely HUGE wasps came hurtling into my conservatory yesterday afternoon. One landed on me which prompted a very hasty retreat upstairs (or in other words I ran for my life). I am terrified of the things. How are you fairing, is your foot any better?
Well its not infected thankfully actually a fair bit better today, just told me to get some e45 cream for the rash and some anti histamines for the iching!
