Suggest Treatment For Ear Pain While Having Cold

Over a year ago I had left ear pain and it felt like my ear was clogged. I went to an ENT who did a hearing test, put a scope down my nose into my throat, tried drops and several antibiotics and anti-inflammatories with no relief. I stopped going because I couldn t afford it and they diagnosed me with left ear pain to my primary physician. I was also having dizzy spells, which have seemed to stop but I still have the clogged ear feeling and can hear a pulsating sound, only in my left ear. Everytime I have gotten a cold in the past year it is worst in my left ear and left side of my throat. Please tell me what to do to make the noise stop.
