Lost Voice, Greenish Mucus Coming From Throat And Having Ear Pain. Any Solution?

Hi I had a cold about a month ago, I lost my voice and all. I never really got my voice back all of the way, and recently I now have this yellow greenish mucus coming out of my throat. My voice is halfway gone again and on top of that I have severe ear pain. I went to the Dr. about five days ago, she said I have a sinus infection and she gave me some antibiotics. My ear is still hurting really bad, I can't hear anything out of my ear, and this smelly discharge is coming out. I bought a ear wax cleaning kit to try to get the thick yellowish stuff out, but I think I should have left my ear alone, because It seems like it hurts worse and is really clogged. I called my Dr she said it may take time for the antibiotics to work I have to take the medicine for the entire ten days and call back if it do not help after that. I think it's something else going on can you please help
