Sounds to me kind of like the "swimmers itch" I used to get sometimes in 
the summer swimming in certain lakes in Minnesota. The biggest key if I 
recall correctly was not to scratch. Hard to do I kno!, I also seem 
to remeber some correlation between this condition and waterfowl 
hanging out on the lake. 
 Just my guess!
