Hi, my teenager has had a sore nose internally for over a week. When I looked at the start of the week it was very red - like the outline of a large blister had popped and red. I had to get a torch to see! The other nostril was also red irritated. She also has a rash on one of her legs at the moment - and I wasn t sure if it coincided - maybe allergic to something. She is taking Razene allergy tablets, but this is not helping the nostril irritation. The full redness has dulled down, but it is still very sore.
