Dear Grace B, did you have any other symptoms accept caught? I am asking becouse I have similar problem. For some four months I caught. I was taking antbiotics only for two months. I took during this four months eks ray of lungs tree times and everything is ok. My GI didn't send my to any other doctor. I only went to immunologist and he also say that it is ok. My problem is thickling feeling in the throat which after a while makes me caught. And during the night I cant sleep becouse this thickling feeling becomes dry throat and makes me caught. That caught is so nasty that for two times now I felt at left side pain in ribs and the pain ended after five days. I think that some nerv was stucked between ribs or some muscles was inflamator as a result of straining during caught. I was taking some herb syrup and pastilles and I caught for few days some mucus. After that my caught became dry. Some times my caught is so ugly and irritative that I have feeling I will throw up. Sorry I write so long but I tried to describe my situation as best I can in short words.
