I’ve written before about how my tics interfere with the way I walk and how they make every step unpredictable. Turning my ankle over is one of the most painful of them. This happens to most people every now and again, but for me it happens many times a day and means that I lurch about even more than normal.

Other walking tics include going up onto my toes, kicking and bending my legs, and suddenly dropping to the floor. These are accompanied by some equally erratic arm and head movements, all of which make walking anywhere with me pretty dramatic.

I had to do a fair bit of walking around today and didn’t have anyone to hold onto. This has made me realise just how difficult and tiring getting about without help has become.
