2 Days Ago Started Coughing, But Nothing Major Like Fever,

2 days ago started coughing, but nothing major like fever, etc.; didn't feel bad at all. Yesterday morning when I was taking my meds, a capsule got stuck in my throat. I tried to get it coughed up, etc., but it burst in my throat. Powder went up my nose and burned my throat. I threw up as I went to get a drink of water, but every time I drank, it would come right back up; this went on for about 15 minutes and finally calmed down. Today, I have almost no voice; sounds like laryngitis. I don't feel bad at all. My question is: should I be worried that I have a burned throat and should I do anything about it? Or is this maybe just a cold-type issue? Or a combo of the perfect storm? :)
