hi..... my nostrils have been staying clogged for over a year now. when the left is clogged the right is fina vice versa. just recently when they clog i have began to have sharp pains in the top of my head like in my skull . the pains are crucial.. then my nose begins to burn and hurt. my nose does not drain often, I have to stick my finger in my nose and press on the sore nostrils to make myself sneeze . does anybody know what this could be?
