Swollen Arm

The bites I got yesterday in France for some reason overnight had caused my arm to swell to twice its normal size and got worse through the day - was marking finalist talks most of the day but as soon as I managed to get home it looked so bad the advice was to go to the nearest walk in centre - after a "happy" 2 hrs waiting in Coventry the doctor gave me some tablets to take - which happily started to work straight away - god bless the NHS!
