question: I am a female, 83 yrs young, up until 2 weeks ago in excellent health... 2 weeks ago I traveled to Hawaii for 4 days, upon returning home I had developed a cough that produced phlegm. After 4 days, I left for 4 days in. NewOrleans where I thought my condition was improving, but to my dismay on my return, it was worse. My eyes developed this yellow crust which is annoying. Should I be worried? What can I do?y
