Girls, I have a problem. My son is 2.7 years old, and for a year now he has had a temperature in his throat every month, red, not coughing or runny nose. He was hospitalized twice, doctors say his immunity is weak, they tested him for bacteria, streptococcus was found, we took Bactriofag Streptococcal, we take antibiotics every time, but it's always the same, every month the same thing, this time we didn't need antibiotics, everything went away in three days, TELL ME WHO HAD THIS? REALLY NEED ADVICE, SOMEONE WHO HAS BEEN THROUGH THIS!
