More Pneumonia?

I am back in the PNW. I am coughing again and the goobies have returned. Is it pneumonia again? I do have seasonal allergies also, although they tend to last all the time. I guess I need to research this. And my knee is not feeling good. I thought maybe it could be the cholesterol lowering pill I am on, but have been off that pill for a week, and maybe it feels a little better, some days. I can't bend it very well. Aging is a incremental process, and I seem to fight this fact and the aging. I can't see myself as old. But if I can't do something, I fret. I guess I will be a whiny old lady and fight it!
