Last Friday evening was spent at drinks in friend's garden (8pm-2am ish).
Woke up Saturday morning with bites on both legs, in gap between trainers and bottom of cropped jeans.
I do tend to react badly but this is something new for UK - intensely itchy red splodges are now huge purple welts with blisters in the middle.
Also, although itching is now dying down, my left foot and ankle is all puffy.
What evil grass dwelling critter does this? And should I worry about the balloon foot?
