Help! What do I have?

Hey. I got sick about 2 weeks ago. I had a sore throat, but i it went away last Monday. I also had seriously bad ear pain one night a few days ago. And every night for the past few weeks my eyes have crusted over when I sleep. I also have a seriously congested nose and I've taken decongestant and inhaled steam. But nothing I do makes it go away. I haven't eaten any dairy products for a few weeks. My nose won't unstuff. And the day before and yesterday I had seriously leg pain. Does anyone know what I have? I would really be thankful and will choose a best answer. Thanks for any answers :D
