I have a terrible burning sensation in my left nostril when breathing thru my nose. Started yesterday when I finished a 3 mile run. As soon as I stepped off the treadmill it hit...sneezing, runny twinge in my nose, watery eye & terrible pain. No headache. I take Allegra D but it has NOT helped at all. Dont laugh but I even had to sleep with cotton & vaseline shoved up my nose. Saline sprays seem to dry out even more & neti pot is no relief. I am undergoing chemo right now. Had 2nd treatment 3-28-13. I know my immune system is weakened & wonder if Im going to have to deal with this thru the rest on my treatment time. I've already had to deal with losing my hair & my life turned upside down & now I cant breathe thru my nose without cringing. Help Me Please!!!!!!!
