Ear congestion and vertigo...ear infection?

For the past few days I have had episodes of vertigo (at least once a day) and pretty bad ear congestion on and off (to the piont of barely hearing). I have had ear infections in the past but usually accompanied by a dull ache in the ear which I do not have now. Today I tried putting several drops of peroxide in my ear but now my ear is more congested! I had read that’s a home remedy for infections. Not sure what to do and I really don’t have the cash for a presciption. Any advice??
