Sinus Medication Solution

If i continue to eat healthy, drink lots of water, and take my vitamins, will the sinus infection just go away? Or do i have to see a doctor?

If so, what are the symptoms & treatments did you/they have? How long did it take for it to be completely cured?

Thanks

P&S section because I just wanted more answers

I am completely frustrated with one doctor in my pediatrician’s practice. He ended up giving me a prescription for an infection anyway, but I was just wondering… I brought my baby in because I suspected a sinus infection, shouldn’t he have looked up her nose? Could he really evaluate a sinus infection by only looking in her ears?

How do i help and comfort someone that has a sinus infection and is on treatment from the doctor to get better?
