Should I be worried

About 3 months ago I got a pedicure and they used that cheese grater thing on my feet which I heard is illegal in some states. Tons of dead skin came off and it was fine for like couple of days. A week later, I had cracking. I’ve had some light peeling on the soft part of my foot after a hot bath previous to this, but this is the worst my feet have been. Took an hour bath so the skin is soft, but when dry, the skin is all dry and just as cracked. Doesn’t hurt but by toes and middle of foot, skin looked chapped. I took it to google and of course it’s saying all these health issues it could be. I do have a thyroid problem, which is being managed and good levels and was told I was insulin resistance in the past but have been fine for almost a year. Should I worry or no?
