That sounds quite uncomfortable. Some forty years ago I broke my right arm, while it was in a splint, healing, I learned to use my left hand and to quite an efficient dexterity too. Once my arm had healed and the splint removed I just went back to using my right hand.
Our English teacher was a very forward thinking fellow, he it was who taught us the Italic style, by writing vee shapes in a line across the page. Having mastered the easier shapes he went on to teach us how to form a curve and finally, how to add flourishes. He helped left handers, there were two in our class, by ordering nibs designed for left handers. There are many styles for those left handed, the one that he encouraged the boys to use had a slightly curved nib. The resulting handwriting was brilliant, I'm sure it gave those two boys much more confidence. The left hand nib looked like this.
