After COVID infection I was diagnosed with kidney injury. Can COVID infection cause kidney pain?

Yes COVID 19 infection can lead to kidney injury. To keep your kidneys from deteriorating avoid any medication that is harmful to your kidney. These include most commonly drugs like Advil and aleve
Dehydration kidney damage can recover with giving fluids. ATN, may need dialysis or recover slowly. There other rare types of kidney damage by covid-19, which may need different treatment modalities.
Kidney injury from Covid-19 is a relatively new phenomenon and it is not known if there is consensus on what exactly happens in the kidney in COVID-19.
Kidney injury in its worst forms is likely to be part of very severe multi-system organ failure from COVID-19, but occasionally isolated kidney injury may occur. However, the kidney injury most of the times means tubular necrosis or interstitial inflammation which most of the time is painless. However, if there is pain over the kidneys, it might be nerve injury or musculoskeletal injury overlying the kidneys. So pain in this case may not be kidney injury.
Kidneys are very sensitive organs, and COVID is a big stress in the body, causing kidney problems directly from the virus and indirectly from the inflammation. As the body recovers, the kidneys also recover from covid. In general, antioxidants, good diet, pro- and prebiotics, and use of steroids for a short time after covid helps with kidneys.
As of my knowledge, it does not cause kidney pain,unless you have lot of protein in the urine from COVID infection then it may cause renal vein thrombosis and can have flank pain.
Usually, kidney injury is not directly from Covid, but is due to low blood oxygen and/or low blood pressure causing kidney injury. However, acute kidney failure with or without Covid can be from usual causes such as volume depletion. Sometimes drugs can cause a systemic allergy or direct toxicity. Older patients can also get urinary retention. Fortunately, most of these conditions will improve, but renal function and urinalysis should be monitored after discharge.
