Should I take these antibiotics despite my family's advice?

[Y0o0o0o0o]

I'm 16. I've had ringing in my ear for most of my life, phlegm always in my throat since I started high school, and have to urinate frequently (~every 40 minutes-1hr)
My doctor prescribed me antibiotics to help fix these problems and clear an infection I apparently have in my ear, and then once I finish the antibiotics, he said he would give me an ear cleaning or refer me to someone who would.

I thought all was good and I should follow the doctor's orders, but my sister, who I feel is knowledgeable on medical things since she wants to become a doctor, told me how antibiotics would be bad for the long run, so now I don't know if I should take the antibiotics

What should I do? Thanks.

Most people take antibiotics at different times in their life.  Your sister's 'wanting' to be a doctor is very different than actually BEING a doctor.  I wouldn't second guess what a licensed physician has recommended to help resolve the problem.  If you have chronic ear infections, you should find out why.  It could be the anatomy of your ear contributing, allergies, etc.  But a glance IN an ear tells a doctor if you have an infection or not. He wants to get that gone and then you can work with the rest of your ear issues.  good luck and let us know how the antibiotics work.  By the way, which one did he prescribe for you?
