why dose my nose hurt when I breath threw it
Perhaps you have a lesion inside it...that could happen easily if you've been in really dry places (winter is the worst time for dryness because we keep the heat turned on). If your nose becomes too dry inside,it could cause craking and you end up with small 'cuts" inside.
Well, is it dry? If it's dry, just don't blow it or do anything. It'll moisten on it's own if it's dry, but it could be another problem.
