question: hi i have been unwell for a week now with constantly coughting , and coughting up green and yellow stuff,i have seen a doctor and have been on antibodies then i was vomiting straight up my food and diaharra I saw another doctor  the  doctor said it could be the antibodies making me vomit and diaharra and changed the antibodies he said I have a chest infection.To use a steamer , cought mix and rest.I just looked at pheumonia site i have the coughting, pain in the chest walls ,the pain is reducing and the fluid i feel in they isnt as bad, its a very chesty cought , it keeps me awake and cant sleep as i start coughting.i had a fever the doctor said I havent had the chills.Just wondering if it could be this and if antibodies will clear it up.Also last year I dated a man who had bad case of bronchis he couldnt get rid of I didnt show any signs of bronchitis then was three months ago.I feel Im improving slowly but still vomiting, coughting alot and starting to lose my voice due to coughting so much.what causing chest infections thanks
