I am athletic (tho no known neck/back problems), and have also spent a lot of time outside and in the sun. I now live in Austin
, Texas, also a sunny climate (but more humid than Colorado), and the dreaded itch came back about a month ago. I can not bear the thought of living with this for the rest of my life. Also, no rash or any other visible sign of itch, aside from the scars I create by scratching until bleeding.
