What Causes Clogging In Nostrils With Dry Cough?

Hi, may I answer your health queries right now ? Please type your query here...hi I am 25 years old and out of the blue I woke up with a dry cough on saturday along with one of my nostrils being very clogged and my head hurting extremely bad. I took some headache medicine and nose drops and felt better. The cough went on through out the day and by that night it got worse. I woke up Sunday and jumped up feeling sweaty and nauseous but never threw up.I had to lay back down and it went away so I went back to sleep. I was again jolted out of bed and stood up,but after a few moments I felt the nausea and sweat start to come back, so I laid down for a few mins and it went away so I proceeded to get back up and was ok. Went back to bed afterwards and just felt pretty bad the cough had slowed but it mad my throat sore and I was feeling achy. After taking another nap I woke up to find that I had a fever of 102.6. My body ached and I had no appetite to eat anything. After a while my chest began to feel a slight tightness and my cough started again.I proceeded to take some tylenol extra strength and some cough medicine and the fever has slowly dropped to 100.0 And my cough is coming and going. My chest feels ok now and my throat is not as sore as before. I am still achy though and feel a little weak. I have been drinking loss of fluids and I was able to eat something. I still feel warm as well and I have a clogged nostril that comes and goes. I am asthmatic as well but my asthma has been controlled by athe advir diskus and my ventolin emergency inhaler.
