A few weeks ago he had to leave work for a few days because he had a bunch of kidney stones he was passing. He was also dehydrated and the doctors at the hospital he went to said his kidneys almost shut down. They monitored him for a few days and released him when all his levels were back to normal.
Recently my dad has been cramping up a lot. He's been drinking water and taking potassium supplements, but it isn't helping. He's also fatigued, has had chills, and is having trouble peeing. We're trying to get him to go get checked out again, but he never has time because he works 60-80 hours a week in an aluminum factory. His hours are unpredictable and he keeps getting forced on a shift whenever he plans to go.
Hopefully we're going to get him there in the next few days, but do you guys have any idea what the problem could be?
He doesn't do any drugs, only drinks lightly and occasionally, but he does smoke and have a fatty diet. He has high blood pressure and he's in his early 40s.
