Allergy

Late in the evening I stood in the warm evening air watering the garden and something bit me on the foot. In the night I must have scratched it. By the morning it was swelling up and red and itchy like mad. Later that day it was moving around my foot skin - it was up my ankle and is now working its way down the foot into my toes. Its a bit freaky. I've only developed this kind of reaction to insect bites recently which I find suprising.
