I have been working on creating my own card spin flourish specific to a gimmick I have been creating as a regular flourish does not work(flourish works on gimmick and regular cards). I have gotten really good at it and can preform the flourish as often as I like. I often while in class spin the card in my hand as I have to fidget and it is way for me to do it in a non-distracting manner. While this is all good, my thumb has all of a sudden in the past day developed a pain in movement of it, a pain that has continually gotten worse since I first noticed it yesterday. I do not have arthritis, however I have been diagnosed with Tendinitis. I am here to ask for advice. Do I continue to practice the routine I have been working on for over a year and just leave the flourish out? Do I stop practicing it in general? Should I take a short break from magic and see if my hand will heal? I'm not sure what I should do, as this routine has been a part of my life for a year+. Even though I haven't preformed the flourish, the simplest things such as texting and other card tricks have increasing the irritation. Help? Thanks!
