How Can severe Vertigo Be Treated?

Hello sir, i have a problem from last year. I feel vertigo and feel like everything around me is floating or sometimes i dont feel balanced but in actual there is nothing like that. I thought it was my thinking. I controlled my self but it didnt work. Now from last two days i face new problem. There is light pain in my left year and sound of air flow. When some vehicle passed from my home i hear strange noise and when it come closer i detect it is vehicle sound.Along these problems am also afraid of heights.Is these all problems related ?? Help me sir. They irritate me alot. Moreover it is bad for my carrer too as canceled my local flights and meeting that was held on high floor. Thankyou
