Does foamy urine which persists even after taking medications indicate kidney disease?

Hello doctor,

I had COVID-19 before two months. I was prescribed Paxlovid but I was also taking Tylenol and Ibuprofen. I had been drinking alcohol quite profusely almost every night for quite sometime before that. Once prescribed, I started noticing that my urine was dark orange no matter how much water I was drinking, and was extremely foamy. Since then, I have stopped drinking alcohol, and my urine has gone back to a regular hay yellow, but it will still get extremely foamy. I also noticed that I was having some general pain in the center of my back on both sides where the kidneys are located. So I went to quite a few doctors and had blood tests done and one finally gave me a urine protein test. My CMP results are as follows: Glucose - 87 mg/dL, sodium - 140 mmol/L, potassium - 3.8 mmol/L, chloride - 104 mmol/L, CO2 - 30 mmol/L, anion gap - 6 mmol/L, BUN - 11 mg/dL, creatinine - 1.12 mg/dL, calcium - 9.4 mg/dL, total protein - 7.6 g/dL, albumin - 4.9 g/dL, alkaline phosphatase - 59 IU/L, AST - 26 IU/L, ALT (SGPT) - 45 IU/L, total bilirubin - 0.5 mg/dL eGFR >90.0 ml/min/1.73m*2. Specific protein urine test result is as follows: Protein Urine - 4 mg/dL, creatinine urine - 94.9 mg/dL, urine protein/creatinine ratio - 42.15 mg/g. On the day of the test, I drank 2 bottles of water (16oz) and urinated one or two times, and had also eaten a turkey sandwich before the test. That being said, is there a chance of me having kidney damage or possibly early CKD? And if not, what could be causing the foam every time I urinate? I know it is foamy because the bubbles are white and they do not go away no matter how long I leave them sitting. Also if I am suspected to have either CKD or proteinuria, what can I do to fix these issues to either make them get better or at least slow or stop further damage?
