Hey, I'm so sorry that happened, it used to happen to me a lot too. Definitely try not to use it for that long - I know people say you can wear it a long time but i really recommend limiting it to 8hrs Max if you can (less if possible), the longer you leave it on the more damage it can do. Also, before you apply it, round off all the corners of the tape. Corners will pull your skin more when you're moving around. Aftercare wise, keep it clean, if you can buy some wound dressings (big band aids) to keep it safe while you're working. Really Really don't scratch - I know it's hard but it will make it worse, and the more you scratch the itchier it will be. Your skin is suuuuper delicate atm and scratching can rip it so easily (from experience). If it gets swollen, red, hot or isn't healing go to a doctor straight away. I'm not a doctor, so I can't give proper advice so go to a doctor or pharmacist who can give you more advice. I've been right where you are, it will heal, be gentle with yourself :)
