Worst cold I've ever experienced

So I flew to Florida about six days ago and I'm not sure if that's what got be sick but I've been congested like crazy, my throat is like a desert, I can't get my damn sneezes out, and to top it off when I flew home the plane right popped only one of my ears and it's still popped and I've lost all hearing in my left ear. Ive tried multiple medications and none work!!! If there are ANY ways I can get rid of this faster... Please help me bc I am frustrated at the fact that I cannot hear.
