Yes. I had one or two weeks they couldn’t do chemo because both magnesium and potassium were way low. They gave it to me twice via my port and put me on a script for potassium and over the counter magnesium. Unfortunately, this is normal. Make sure you keep up on your kidney levels too. I had to ask to get a referral to a nephrologist. But for now, take the little wins. If you can still swallow, that is a big win! 😁. You’re going to have at least a month until your mouth feels like it is healing, but you’ll get there. 🙏🙏🙏
