"sinusitis" Not sure what that is...can look it up in a few minutes, but I don't believe so...why do you ask?

[CJ Wolf]

Chronic sinus problems, sometimes a sinus problem can drip into the lungs, leads to infection. Sometimes it's not that obvious that it is occuring since it's leaking down the throat usally when the person is sleeping.

It may come and go with alergies and viruses.

Check out the environment she lives in as well. You may find a source of infection that is not obvious, such as the airconditioning system, leading to possible airborne fungus, bacteria and such.

It's sad about your sister, but your faith will see you and her through these tough time. God Bless.
