Vertigo, Head Pressure, Headaches, Foot Numbness. Taking Flonase. Will Augmentin Help?

Hi, I ve been having vertigo , I even feel it when I m laying down sometimes. I also have a white light that moves down the corner of my head periodically and head pressure, headaches. I had this last year for months, don t want to be out of it again. Also getting numbness in my foot, wasn t sure if these could all be neuropathy related or inner ear . I was put on Z-Pak and it didn t help, also Flonase . I was also given Augmentin , do you think that s worth a try? I remember it hurting my stomach a few years ago. Thanks!
