I am battling allergies and a cold , so have the common symptoms: runny nose , sneezing , watery eyes, sinus headache. However, I have a different symptom than before. Just inside my nostrils is extremely tender and has a thin yellow sticky substance. When it dries (when I finally stop sneezing for awhile), it becomes like a scab in my nose. It s very painful, especially when I blow my nose. If I try to take it out, it is also painful. How can I get this to heal?
