I am a 23 year old, and for the past 2 years or so, every few months have been getting what seems like a respirtory infection. Usually lasts several months. This time it is the worst. So far it's only been three days, but I have experienced chest pain when breathing (which is gone right now) I am dizzy, weak, having trouble talking because I can't catch my breath very well when I do, My cough brings up a white frothy sputum with ALMOST SLIGHTY a yellowish tint to it, I have had fevers, and have also been going through periods when I am sweating and then almost immediately freezing and back and forth constantly for two days... I just don't know what to do! The more I look up, it could either be a cold, or something serious. Also, I seem to have a small drooling problem and when I inhale and exhale I can hear a wheezing and bubbling sound.
