I can breathe through my nose pretty well, but it really hurts to take a deep breathe in. This has been an issue for about 3 weeks now. Went to my dr. last week and was given Rx for Amoxicillan and told that I am having nasal drainage which is irritating my chest. Low grade temperature persists and it really hurts to breathe deep or talk - it isn t my throat that hurts, but the upper part of my chest. Any idea if this will go away on its own?
