I was staying still in skyrim. (Because I was on the laptop)
Then my player coughs!
I think it was because he has 3 diseases (I know, I should go get healed lol).
I go to post this and throughout he has kept sniffing.

Has this always happened?
And it isn't anyone else, I am in the middle of nowhere.

Haha yeah, it's strange the first time it happens. Only some illnesses cause audible symptoms like that. Your character will also cough when around poisonous gasses.

Welcome to the forum, new person!

I don't remember my player-character doing this, although my follower does.

edit: typo

I have never heard my character do this, but I am pretty good about visiting a shrine in each town and getting a blessing. The chances of getting a disease from an individual attack are high enough that 3 or 4 fights results in a disease in this game. Because of that, I get blessed everywhere I go. I don't even care what the effects of the blessing are, I just want the disease gone.
