How Can Vertigo Be Treated?

I contacted a virus about 6 weeks ago...I have tried everything from daily netti pot use, allegra, steroidal nasal sprays and holistic supplements. After 3 weeks I went to my Primary care doctor and he put me on Augementin for 10 days...I have been off of the Augementin for almost 4 weeks. At around the time I started on the Augmentin, I started having vertigo. This has been going on now for over 4 weeks...I feel like I am losing my mind...I am a 61 year old healthy female who does not smoke or drink excessively. I try to exercise (at least power walk) every day but have not been able to do so for the past 4 weeks due to the vertigo...I was researching to see if maybe a round of steroids would help??
