Folic thanks for asking, I think I feel a bit better today, thanks! Although, I had my shower this morning and was rubbing moisturiser into my leg and realised it was swollen, and of course, I am such an anxious, panicky type that I'm thinking 'aaaah, I have a tumour on my leg' 
. My GP is closed for two days, and its not an emergency, so I have to spend the next couple of days in a panic, heart pounding. Of course, as DH pointed out, I did get sunburnt there on hols (normally very careful with the sunscreen, being fair and freckly, but had a mishap!) and have spent the past week scratching at the mad itch, so it's no wonder my leg has swollen a bit (it's very localised). Anyway, sure enough, six hours later and I finally plucked up the courage to pull up my trouser leg and peep at my leg and the swelling has gone back down to being barely noticeable. DH despairs of me sometimes, says he has never met anyone who can have or see the simplest, most easily explained symptom, and immediately assume that it's fatal, but the anxiety is something I have struggled with on and off for years. Although, I must say, he is very good too, he sort of rolls his eyes, but he understands that it's very real to me, so he never laughs or gets angry or anything.
