Karen,
I was really glad to hear you describe your throat and how it feels in cold weather and while walking. I was beginning to wonder if there was something wrong with my throat. (I know - I meant besides the normal what's wrong with your throat)
I was in cold weather (-10 wind chill) last week and my throat was really painful. It still hurts a bit even in San Antonio weather, but last week was tough. Nice to know that it's not something new.
Take care,
Dinah
