retraction of eardrum

My daughter has been miserable for weeks with what looked like an ear and sinus infection.  The doctor told her she had retraction and infection. He gave her an antibiotic and when she went back about 3 weeks later nothing had changed so he gave her another antibiotic.  She now gets very car sick and dizzy when riding with others but she doesn't have this problem when she drives herself.  She has terrible headaches and dizziness a lot tho.  Her new job is to drive up and down a very steep mountain twice a day.  Could this change in altitude be a major factor?

Did they say anything about the pressure inside the ear?

Two treatments of antibiotics has devastating effect on the bacterial flora in the intestines and could very well be the cause of flaring infections (i speak from experience).

I suspect your daughter has misbehaving Eustachian tube and retraction/fluid in the middle ear.  I agree that giving her more antibiotics is not likely to help this, but disagree that 2 courses of antibiotics has "devastating effects" on the bacterial flora and is now somehow the cause of her "flaring infections".  Taking antibiotics will likely alter the make-up of the intestinal flora, but this most often goes unnoticed by the individual, changes once the treatment is stopped (we eat bacteria every day) and has not be shown to cause infections on a wide scale (there are some who can have problems when one type of bacteria is allowed to overgrow).

Patients with the symptoms your daughter describes often have middle ear fluid, but this is not necessarily infected fluid -- and I doubt your daughter still has an "infection" in her ear.  Regardless, if it causing this degree of trouble, there are things an ENT doc can do to help her.  And yes, changes in altitude would only be making this worse for her.
