I hope your weeding works GG.
One of mine was stung by a European wasp last year - on her face. She came up in huge welts and swellings around her head and neck. Over the next few weeks, whenever she got hot they would come up again, but anywhere on her head, body and legs. Nasty. We had to take her everywhere with us to keep an eye on her in case she swelled around her throat and had trouble breathing. Cool wet towels and ice packs helped.
Our vet didn't want to medicate her unless really desperate to help her body develop resistance to the toxin naturally. But I certainly hope she never finds another one!
