Hello. I Was Painting My Sons Room Yesterday And Forgot

Hello. I was painting my sons room yesterday and forgot to open the windows. This was an all day project. I felt fine until I woke this morning and feel tired. Throughout the day, I developed a nagging, dry cough. It progressively has gotten worse. I took a nap and hot shower. I now feel like my throat is on fire, cant stop coughing, and my chest is tight. Help??
