Hi, I have had a cough for over 3 weeks now, and in the middle week I also developed a flu, aches pains, high temp, runny nose, my runny nose has eased and so has my cough, but now I have thick clear phelmg like stuff coming from my nose and when I cough It just sounds really phelmg. Yesterday and today I have started to develop a severe pain under my left breast on my rib cage it really hurts to cough and breath in,
