Yeah I can relate to that! Sitting at a computer 8 hours a day at work can cause very bad back problems, I never had any until the beginning of the year when I was flat on my back for a couple of weeks with excruciating lumbar pain. The doc said to make sure I get up at least 5 mins every hour and stretch. Never get any pain while exercising - think it's because sitting in a chair in front of a pc you are generally in the same position all the time. Anyway, I've put this on another thread, but I swear by an American product called Air Cast - it's 2 rigid plastic pieces with a material strip that goes under your foot, and it's held on with Velcro straps, once you have it on air is pumped into the side bits until they fit your calf properly. It's designed to be worn with running shoes, and once on you can run almost normally, certainly can bike, and it shortens recovery time. Both my husband John and myself suffered ankle injuries a couple of weeks before Ironman triathlon (though in different years)and both of us managed to complete the event after using Air Cast to recover. You can begin to walk and run normally as soon as the swelling goes down. John actually did Ironman while wearing his!
