Nephrotic syndrome. Us with ur answer.

My son was hospitalized in dec 2019 and doctor confirmed that he got nephrotic syndrome and treatment was done. We used medicine for 2 months. after all this he is normal. Again he got symptoms of nephrotic syndrome in May 2020, we consult the previous doctor for the same. He prescribed medicine for one month and then he is normal. He got the same problem again last week we consult nephrologist, doctor prescribed other medicine. We used this medicine from last 5days and my child got swelling at scrotum. Today morning he got tested for urine protine creatine ratio. The result is Urine protein :15 Urine creatinine: 163 Proteins/creatinine Ratio: 0.09 We are worried that he is in Normal condition or any serius condition. Plz 🙏do help us with ur answer.
