Last winter i got the flu shot and this all began about a week after. I`m not sure what this is either but it drives me crazy! Every two weeks i get this horibble cough and i get a stuffy/ runny nose. I get bout 2-3 days off from it and bam! its back again! On occasion this will com but comes with headaches/ sore throt for about 1-2 days.For the whole two weeks its majority coughing and runny/ stuffy nose. Its the same symptoms again this winter. Today i coughed up streeks of blood in my mucus for the first time, does anybody have any idea what all this is? Mind u sometimes i get chest pains as well, but thats only happened a few times.
