I believe I am suffering from vertigo in my left ear and would like to know if there are any treatments out there. Also, is there an almost definite way to determine whether I do without going to the dr?

It's in your best interest to see a dr. it may or may not be a serious problem causing it and only a dr will be able to help you determine if it is and what the best treatment will be.
