I started having pain in my kidney area last week that would come and go. It now really hurts constantly. I also have a headache and nausea. No fever, no UTI symptoms. What should I do? Should I be worried?

Get a diagnosis. For every symptom there are hundreds of diagnosis so you can't really tell without a check up

What should you do... you should see a doctor to get properly diagnosed in case it's something serious.

We really can't tell you what's going on with one post online. Do you have x-rays you can post, results from urine tests, blood tests, any test done that you can post?

Do you see the problem here? We can guess, that's all. Diagnosing, even if you posted everything I listed, is impossible to do on the internet.

You need to see an actual doctor to find out what's going on.

Good luck.

Yes, I would worry, kidney issues can be serious, and need to be checked.
