Brief Answer:
May be kidney stone or infection:

Detailed Answer:
Hello and welcome,

Right sided flank pain along with nausea is likely to be something going on with your right kidney. This could be a stone or infection. Less frequently other there can be other abnormalities of the kidney.

Stones can cause a lot of pain. An infection can cause nausea and vomiting. Usually there is also a fever and people feel overall ill with a kidney infection, but it needs to be ruled out.

I recommend that you go in to your doctor, if you can get in today, or an urgent care center. They should take a urine sample for a full urinalysis, and if any signs of infection on the "dip urine" test (which can be done while you are there), then the urine specimen should be sent for "culture and sensitivity testing". The sensitivity test shows which antibiotics the bacteria (if any) are sensitive to.

An X-ray should also be done - this can show if there is a calcium based stone. If none of this reveals anything, then a renal ultrasound (which is non-invasive) should be done. If a stone is seen, it should be assessed for size to see whether it will be able to pass with hydration only. Then they should give you a strainer to pass urine through (to catch the stone when it comes out), and pain medication.

So please go in now to get this sorted out. I hope this information helps get you started. I welcome letting me know how you are doing after you have been evaluated.
