Dry cough, chest pain, breathing problems, dizzy.?

Hey, sounds like you have it really bad. I am a nursing istant. Your symptoms sound like you have a really bad case of pneumonia. It is sometimes called "walking pneumonia" where I am from, because you go around sick for a while then it really knocks you down. If that is what you have, it takes about two to four weeks to get better. I usually can't feel the medicine helping me until I have about finished it all. I have had it so bad that it took two different antibiotics to get me better. You are right about the cold air being bad for you. Stay out of it all you can. If you must go out, wrap a scarf around your neck and cover your mouth. Breath through your scarf with your mouth, it warms the air as you breath it in. I hate to tell you this but it is true. The very best thing you can do is stay out of work until you feel a lot better, that is the only thing that will help, lots and lots of rest. It just has to run its course. Another thing you could consider is asthma, but you need to go to a specialist and be diagnosed for that. Oh yeah, good job on drinking things that are good for you and NOT smoking! If you don't feel better by Friday the 7th I would be going back to the doctor and asking for a better anti-biotic. Keep sleeping the way you are, it helps with your breathing at night. Do not stay too hot either as this will worsen your symptoms. A tablespoon of honey also helps wth the coughing. If you have something called Vick's vapor rub, you can rub it in your chest. It helps with a lot of your symptoms. Sorry this is so long, but I tried to help all I could Good Luck :)
