There are great deal of things you need to consider, somebody mentioned going by train but in some of us the vibrations as it goes over the rail joints would be agony, I cannot have any material on my arm so clothing is no good to me. I have also had a spread caused by a sensitivity pin used 4ins outside the affected area and it started in both legs when my grandson trod on my toes.
I am also one of the 7 - 8% on whom any wound may never heal, flying Ant Bites still visible from 22 july 11 and 2 acupuncture wounds from 19Jan 2010
