My son is 4 years old and he has had about 16 year infections since he was about 6 months old. He had to end up getting tubes in his ear last year but has only had 1 ear infection since this year. Because he was on so many antibiotics his immune system is so low and he catch everything that s going around at his school. Now he s having a problem when he go to the bathroom when he go to pee it hurt. His feet and hand are always cold he s had a runny nose an now a little cough. Took him to the emergency room they said it s a virtual utility never heard this before. I need some answers. Oh yeah he s been on probiotics for a month and a half now. Someone told me about colloidal silver I bought but not sure if I should use it. Help don t know what to do.
