Nose

My nose is really sore again. Feels like someone hit me on the right side, but there's no bruise. My doctor had theorized that the nose pain I had last month was sun-related. This new occurance started after I was out in the sun for a good 45 minutes, so maybe? But why would a burn make it feel like the underlying membranes were injured? And only on the one side now? I don't get it.
