I was left handed. Tried to write that way at school, but it was the theory then that you could be forced to learn with your right hand (early 70s) and I was made to do so.
Then having sorted life out, writing mostly with my right hand, but doing everything else left handed, I hurt my wrist in a simple accident. I didn't know it at the time but I have hypermobility syndrome and the damage to the tendons in this accident meant that they couldn't prevent my wrist dislocating 20-30 times a day. I spent 13 years with my left wrist in plaster until I threatened to sever the nerves in my arm myself if something wasn't do to deal with the pain I was in. I couldn't cope anymore with the chronic pain I was living in, pure and simple. After that I actually got the treatment it needed. I was referred to the top wrist specialist in the country who quickly diagnosed some if the problem. Out turned out it was dislocating in 2 different places, not one. After numerous operations (11 i think) and various nerves removed, dead bones removed, others shortened and tendons also shortened I now have a wrist that doesn't hurt too much and only dislocate maybe once it twice a month. I can cope with that. But I never ever managed to work out how to iron with my right hand and not actually burn my left hand ginger tips. I don't have that coordination. Ironing went out of the window.
