Wakeup with frequent nasuea an mild kidney pain was told catscan was clear ahowed kidney stones in kidneys can they be causing my problem also bloatin?

Probably: If your ct scan shows kidney stones, yes, they are most likely causing kidney or flank pain, nausea. If they don't pass on their own, you might see about getting a urology referral.

Yes: Kidney stones can certainly cause nausea and bloating. They will also cause kidney pain. But one thing in your question is not clear .... Was cat scan normal? If it was normal, you do not have kidney stones. Cat scans are very good for picking those up.
