Suggest Treatment For Persistent Cold And Blocked Ears

Ive had a cold for about 5-7 days now and ive been trying to fight it naturally with no medicine involved, today my cold was in what i called the dying stage.The last major coughs, blowing of nose but then suddenly my right ear went completely clogged on me. Ive never had this happen to me before i acutally thought I was going deaf because how dramatically my hearing ability was limited. My ear felt as if thier was some type of air bubble growing slowy and causes more and more blockage. Little yawns or jaw strecthes wouldn t do nothing at all in the beginning but not small yawns tend to hurt just a little in the inside of my ear. I would like to know where did this feeling suddenly come from and what could i do
